Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 2 and earlier, 6 Update 30 and earlier, and 5.0 Update 33 and earlier allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Concurrency. NOTE: the previous information was obtained from the February 2012 Oracle CPU. Oracle has not commented on claims from a downstream vendor and third party researchers that this issue occurs because the AtomicReferenceArray class implementation does not ensure that the array is of the Object[] type, which allows attackers to cause a denial of service (JVM crash) or bypass Java sandbox restrictions. NOTE: this issue was originally mapped to CVE-2011-3571, but that identifier was already assigned to a different issue.

A remote code execution vulnerability exists within multiple subsystems of Drupal 7.x and 8.x. This potentially allows attackers to exploit multiple attack vectors on a Drupal site, which could result in the site being compromised. This vulnerability is related to Drupal core - Highly critical - Remote Code Execution - SA-CORE-2018-002. Both SA-CORE-2018-002 and this vulnerability are being exploited in the wild.

Directory traversal vulnerability in RequestUtil.java in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.65, and 8.x before 8.0.27 allows remote authenticated users to bypass intended SecurityManager restrictions and list a parent directory via a /.. (slash dot dot) in a pathname used by a web application in a getResource, getResourceAsStream, or getResourcePaths call, as demonstrated by the $CATALINABASE/webapps directory.

A missing bounds check was found in the way OpenSSL handled TLS heartbeat extension packets. This flaw could be used to reveal up to 64k of memory from a connected client or server.

Only 1.0.1 releases of OpenSSL are affected including 1.0.1f (and 1.0.2 betas)

The following upstream commit introduced TLS/DTLS heatbeat support and also this issue:

Plexus-utils before 3.0.16 is vulnerable to command injection because it does not correctly process the contents of double quoted strings.

In postgresql 9.3.x before 9.3.21, 9.4.x before 9.4.16, 9.5.x before 9.5.11, 9.6.x before 9.6.7 and 10.x before 10.2, pgupgrade creates file in current working directory containing the output of pgdumpall -g under umask which was in effect when the user invoked pgupgrade, and not under 0077 which is normally used for other temporary files. This can allow an authenticated attacker to read or modify the one file, which may contain encrypted or unencrypted database passwords. The attack is infeasible if a directory mode blocks the attacker searching the current working directory or if the prevailing umask blocks the attacker opening the file.

It was found that Apache Solr would accept an object from an unauthenticated user that could be manipulated through subsequent post requests. An attacker could use this flaw to assemble an object that could permit execution of arbitrary code on the server.

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.

In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, epan/dissectors/packet-giop.c has a memory leak.

In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, epan/dissectors/packet-smb2.c has a memory leak.

In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the NBAP dissector could crash with a large loop that ends with a heap-based buffer overflow. This was addressed in epan/dissectors/packet-nbap.c by prohibiting the self-linking of DCH-IDs.

In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the IEEE 802.15.4 dissector could crash. This was addressed in epan/dissectors/packet-ieee802154.c by ensuring that an allocation step occurs.

In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the Kerberos dissector could crash. This was addressed in epan/dissectors/packet-kerberos.c by ensuring a nonzero key length.

In Wireshark 2.4.0 to 2.4.5, the TCP dissector could crash. This was addressed in epan/dissectors/packet-tcp.c by preserving valid data sources.

libming 0.4.8 has a NULL pointer dereference in the getInt function of the decompile.c file. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted swf file.

In GraphicsMagick 1.3.28, there is a divide-by-zero in the ReadMNGImage function of coders/png.c. Remote attackers could leverage this vulnerability to cause a crash and denial of service via a crafted mng file.

In libming 0.4.8, there is a use-after-free in the decompileJUMP function of the decompile.c file.

In LibTIFF 4.0.9, a heap-based buffer overflow occurs in the function LZWDecodeCompat in tiflzw.c via a crafted TIFF file, as demonstrated by tiff2ps.

A flaw was found in the way the Linux kernel handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, processor does not deliver interrupts and exceptions, they are delivered once the first instruction after the stack switch is executed.

An unprivileged system user could use this flaw to crash the system kernel resulting in DoS.

Incorrect buffer length handling in the ncpreadkernel function in fs/ncpfs/ncplibkernel.c in the Linux kernel through 4.15.11, and in drivers/staging/ncpfs/ncplibkernel.c in the Linux kernel 4.16-rc through 4.16-rc6, could be exploited by malicious NCPFS servers to crash the kernel or execute code.

Dir.open, Dir.new, Dir.entries and Dir.empty? accept the path of the target directory as their parameter. If the parameter contains NUL (\0) bytes, these methods recognize that the path is completed before the NUL bytes. So, if a script accepts an external input as the argument of these methods, the attacker can make the unintentional directory traversal.

Affected versions:

Ruby 2.2 series: 2.2.9 and earlier Ruby 2.3 series: 2.3.6 and earlier Ruby 2.4 series: 2.4.3 and earlier Ruby 2.5 series: 2.5.0 and earlier

In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, the UNIXServer.open and UNIXSocket.open methods are not checked for null characters. It may be connected to an unintended socket.

If an attacker sends a large request which contains huge HTTP headers, WEBrick try to process it on memory, so the request causes the out-of-memory DoS attack.

Affected versions:

Ruby 2.2 series: 2.2.9 and earlier Ruby 2.3 series: 2.3.6 and earlier Ruby 2.4 series: 2.4.3 and earlier Ruby 2.5 series: 2.5.0 and earlier

In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an attacker controlling the unpacking format (similar to format string vulnerabilities) can trigger a buffer under-read in the String#unpack method, resulting in a massive and controlled information disclosure.

Roland Gruber Softwareentwicklung LDAP Account Manager before 6.3 has XSS via the dn parameter to the templates/3rdParty/pla/htdocs/cmd.php URI or the template parameter to the templates/3rdParty/pla/htdocs/cmd.php?cmd=renameform URI.

A directory traversal flaw in SquirrelMail 1.4.22 allows an authenticated attacker to exfiltrate (or potentially delete) files from the hosting server, related to ../ in the attlocalname field in Deliver.class.php.

In Apache Batik 1.x before 1.10, when deserializing subclass of AbstractDocument, the class takes a string from the inputStream as the class name which then use it to call the no-arg constructor of the class. Fix was to check the class type before calling newInstance in deserialization.

In libvips before 8.6.3, a NULL function pointer dereference vulnerability was found in the vipsregiongenerate function in region.c, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted image file. This occurs because of a race condition involving a failed delayed load and other worker threads.
