A crafted request uri-path can cause modproxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.
In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code.
In Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8. ...
An XML deserialization vulnerability was discovered in slf4j's EventData, which accepts an XML serialized string and can lead to arbitrary code execution.
A flaw was found in the bash functionality that evaluates specially formatted environment variables passed to it from another environment. An attacker could use this feature to override or bypass restrictions to the environment to execute shell commands before restrictions have been applied. Certain services and applications allow remote unauthenticated attackers to provide environment variables, allowing them to exploit this issue.

Red Hat would like to thank Stephane Chazelas for reporting this issue.
A heap overflow vulnerability was found in openslp, that may result in remote code execution.
apachemodphp. Multiple issues were addressed by updating to PHP version 7.3.11.
A flaw was found in the Linux kernel. A heap based buffer overflow in mwifiexuapparsetailies function in drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory corruption and possibly other consequences.
A flaw was found in the implementation of transport.py in Paramiko before 1.17.6, 1.18.x before 1.18.5, 2.0.x before 2.0.8, 2.1.x before 2.1.5, 2.2.x before 2.2.3, 2.3.x before 2.3.2, and 2.4.x before 2.4.1 does not properly check whether authentication is completed before processing other requests, as demonstrated by channel-open. A customized SSH client can simply skip the authentication step.

An issue was discovered in LibVNCServer through 0.9.11. rfbProcessClientNormalMessage() in rfbserver.c does not sanitize msg.cct.length, leading to access to uninitialized and potentially sensitive data or possibly unspecified other impact (e.g., an integer overflow) via specially crafted VNC packets.
A flaw was found in libreoffice. Arbitrary remote file disclosure may be achieved by the use of the WEBSERVICE formula in a specially crafted ODS file.

In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection.
A use-after-free vulnerability can occur while parsing an HTML5 stream in concert with custom HTML elements. This results in the stream parser object being freed while still in use, leading to a potentially exploitable crash.
The ISAKMP parser in tcpdump before 4.9.0 has a buffer overflow in print-isakmp.c:ikev2eprint().
The IPv6 parser in tcpdump before 4.9.0 has a buffer overflow in print-ip6.c:ip6print().
The BOOTP parser in tcpdump before 4.9.0 has a buffer overflow in print-bootp.c:bootpprint().
The ISO CLNS parser in tcpdump before 4.9.0 has a buffer overflow in print-isoclns.c:clnpprint().

It was discovered that the RMI (Java Remote Method Invocation) server implementation in the JMX (Java Management Extensions) component of OpenJDK did not restrict which classes can be deserialized when deserializing authentication credentials. A remote unauthenticated attacker able to connect to a JMX port could possibly use this flaw trigger deserialization flaws.
An unspecified flaw was found in the Libraries component in OpenJDK. ObjectInputStream's readSerialData() could, in certain cases, incorrectly perform deserialization of data from serialized input. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.
GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the modcgi and modcgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.
Use-after-free vulnerability in the nsHostResolver::ConditionallyRefreshRecord function in libxul.so in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via vectors related to host resolution.
The nsXBLProtoImpl::InstallImplementation function in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 does not properly check whether objects are XBL objects, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow) via crafted JavaScript code that accesses a non-XBL object as if it were an XBL object.
Use-after-free vulnerability in the TypeObject class in the JavaScript engine in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allows remote attackers to execute arbitrary code by triggering extensive memory consumption while garbage collection is occurring, as demonstrated by improper handling of BumpChunk objects.
Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allow remote attackers to bypass the popup blocker via unspecified vectors.
The Web IDL implementation in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allows remote attackers to execute arbitrary JavaScript code with chrome privileges by using an IDL fragment to trigger a window.open call.
vmtypedarrayobject.cpp in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 does not validate the length of the destination array before a copy operation, which allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds write and application crash) by triggering incorrect use of the TypedArrayObject class.
The libxul.so!gfxContext::Polygon function in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allows remote attackers to obtain sensitive information from process memory, cause a denial of service (out-of-bounds read and application crash), or possibly bypass the Same Origin Policy via vectors involving MathML polygon rendering.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
