A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.

A flaw was found in Apache Santuario (XML Security for Java) in the way it processed some paths. A remote attacker could use this flaw to circumvent the "secure validation" feature and disclose potentially sensitive information in local XML files.

An unspecified vulnerability in Java SE related to the Libraries component could allow an unauthenticated attacker to cause no confidentiality impact, high integrity impact, and no availability impact.

A flaw was found in the way the readObject() method of the MethodType class in the Libraries component of OpenJDK checked argument types. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

A flaw was found in the boundary checks in the java.nio buffer classes in the Libraries component of OpenJDK, where it is bypassed in certain cases. This flaw allows an untrusted Java application or applet o bypass Java sandbox restrictions.

AMD. A buffer overflow issue was addressed with improved memory handling.

An information leak flaw was found in the Linux kernel’s IPv6 implementation in the ipv6selectident in net/ipv6/outputcore.c function. The use of a small hash table in IP ID generation allows a remote attacker to reveal sensitive information.

A deserialization flaw was discovered in the jackson-databind that could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper. This issue extends the previous flaws CVE-2017-7525 and CVE-2017-17485 by blacklisting more classes that could be used maliciously.

A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source port randomization are indirectly affected as well.

ASN.1 strings are represented internally within OpenSSL as an ASN1STRING structure which contains a buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings which are repesented as a buffer for the string data which is terminated with a NUL (0) byte. Although not a strict requirement, ASN.1 strings that are parsed using OpenSSL's own "d2i" functions (and other similar parsing functions) as well as any string whose value has been set with the ASN1STRINGset() function will additionally NUL terminate the byte array in the ASN1STRING structure. However, it is possible for applications to directly construct valid ASN1STRING structures which do not NUL terminate the byte array by directly setting the "data" and "length" fields in the ASN1STRING array. This can also happen by using the ASN1STRINGset0() function. Numerous OpenSSL functions that print ASN.1 data have been found to assume that the ASN1STRING byte array will be NUL terminated, even though this is not guaranteed for strings that have been directly constructed. Where an application requests an ASN.1 structure to be printed, and where that ASN.1 structure contains ASN1STRINGs that have been directly constructed by the application without NUL terminating the "data" field, then a read buffer overrun can occur. The same thing can also occur during name constraints processing of certificates (for example if a certificate has been directly constructed by the application instead of loading it via the OpenSSL parsing functions, and the certificate contains non NUL terminated ASN1STRING structures). It can also occur in the X509get1email(), X509REQget1email() and X509get1ocsp() functions. If a malicious actor can cause an application to directly construct an ASN1STRING and then process it through one of the affected OpenSSL functions then this issue could be hit. This might result in a crash (causing a Denial of Service attack). It could also result in the disclosure of private memory contents (such as private keys, or sensitive plaintext). Fixed in OpenSSL 1.1.1j (Affected 1.1.1-1.1.1k). Fixed in OpenSSL 1.0.2za (Affected 1.0.2-1.0.2y).

A heap-based buffer overflow was found in libxml2 when processing truncated UTF-8 input.

GNU C Library (aka glibc or libc6) is vulnerable to a denial of service, caused by an assertion failure when processing invalid input sequences in the ISO-2022-JP-3 encoding in the iconv function. By sending specially-crafted input, a remote attacker could exploit this vulnerability to cause the application to crash.

A flaw was found in the Serialization component of OpenJDK handled serialization filter. A process-wide filter could have been modified by setting jdk.serialFilter system property at runtime, possibly leading to a bypass of the intended filter during deserialization.

A memory leak in the fastrpcdmabufattach() function in drivers/misc/fastrpc.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering dmagetsgtable() failures, aka CID-fc739a058d99.

A memory leak in the adisupdatescanmodeburst() function in drivers/iio/imu/adisbuffer.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-9c0530e898f3.

A memory leak in the adisupdatescanmode() function in drivers/iio/imu/adisbuffer.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-ab612b1daf41.

A memory leak in the gscanopen() function in drivers/net/can/usb/gsusb.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usbsubmiturb() failures, aka CID-fb5be6a7b486.

A memory leak in the rpmsgeptdevwriteiter() function in drivers/rpmsg/rpmsgchar.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering copyfromiterfull() failures, aka CID-bbe692e349e2.

An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vividstopgeneratingvidcap(), vividstopgeneratingvidout(), sdrcapstopstreaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.

A flaw in the kernels implementation of ptrace which could inadvertantly grant elevated permissions to an attacker who could abuse the relationship between tracer and the process being traced.

The mechanism used to link the process requesting the ptrace and the process being ptraced could allow a local user to obtain root level priviledges by creating an opportunity to abuse the frequently used pattern of dropping privileges and then execve a child with reduced privileges/permissions.

Impact When using SSL/TLS with Jetty, either with HTTP/1.1, HTTP/2, or WebSocket, the server may receive an invalid large (greater than 17408) TLS frame that is incorrectly handled, causing CPU resources to eventually reach 100% usage.

Workarounds

The problem can be worked around by compiling the following class: java package org.eclipse.jetty.server.ssl.fix6072;

import java.nio.ByteBuffer; import javax.net.ssl.SSLEngine; import javax.net.ssl.SSLEngineResult; import javax.net.ssl.SSLException; import javax.net.ssl.SSLHandshakeException;

import org.eclipse.jetty.io.EndPoint; import org.eclipse.jetty.io.ssl.SslConnection; import org.eclipse.jetty.server.Connector; import org.eclipse.jetty.server.SslConnectionFactory; import org.eclipse.jetty.util.BufferUtil; import org.eclipse.jetty.util.annotation.Name; import org.eclipse.jetty.util.ssl.SslContextFactory;

public class SpaceCheckingSslConnectionFactory extends SslConnectionFactory { public SpaceCheckingSslConnectionFactory(@Name("sslContextFactory") SslContextFactory factory, @Name("next") String nextProtocol) { super(factory, nextProtocol); }

@Override protected SslConnection newSslConnection(Connector connector, EndPoint endPoint, SSLEngine engine) { return new SslConnection(connector.getByteBufferPool(), connector.getExecutor(), endPoint, engine, isDirectBuffersForEncryption(), isDirectBuffersForDecryption()) { @Override protected SSLEngineResult unwrap(SSLEngine sslEngine, ByteBuffer input, ByteBuffer output) throws SSLException { SSLEngineResult results = super.unwrap(sslEngine, input, output);

if ((results.getStatus() == SSLEngineResult.Status.BUFFERUNDERFLOW || results.getStatus() == SSLEngineResult.Status.OK && results.bytesConsumed() == 0 && results.bytesProduced() == 0) && BufferUtil.space(input) == 0) { BufferUtil.clear(input); throw new SSLHandshakeException("Encrypted buffer max length exceeded"); } return results; } }; } } This class can be deployed by: + The resulting class file should be put into a jar file (eg sslfix6072.jar) + The jar file should be made available to the server. For a normal distribution this can be done by putting the file into ${jetty.base}/lib + Copy the file ${jetty.home}/modules/ssl.mod to ${jetty.base}/modules + Edit the ${jetty.base}/modules/ssl.mod file to have the following section:

[lib] lib/sslfix6072.jar

+ Copy the file ${jetty.home}/etc/jetty-https.xml and${jetty.home}/etc/jetty-http2.xml to ${jetty.base}/etc + Edit files ${jetty.base}/etc/jetty-https.xml and ${jetty.base}/etc/jetty-http2.xml, changing any reference of org.eclipse.jetty.server.SslConnectionFactory to org.eclipse.jetty.server.ssl.fix6072.SpaceCheckingSslConnectionFactory. For example: xml <Call name="addIfAbsentConnectionFactory"> <Arg> <New class="org.eclipse.jetty.server.ssl.fix6072.SpaceCheckingSslConnectionFactory"> <Arg name="next">http/1.1</Arg> <Arg name="sslContextFactory"><Ref refid="sslContextFactory"/></Arg> </New> </Arg> </Call> + Restart Jetty

A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients.

An out-of-bounds read in cmstypes.c in TypeMLURead function was found, leading to heap memory leak triggered by crafted ICC profile.
