Apache Standard Taglibs before 1.2.3 allows remote attackers to execute arbitrary code or conduct external XML entity (XXE) attacks via a crafted XSLT extension in a (1) <x:parse> or (2) <x:transform> JSTL XML tag.

An issue was found in the Linux kernel ipv6 implementation of GRE tunnels which allows a remote attacker to trigger an out-of-bounds access. At this time we understand no trust barrier has been crossed and there is no security implications in this flaw.

A flaw was found in ImageMagick 7.0.7-25 Q16. WriteEPTImage function in coders/ept.c allows remote attackers to cause a denial of service (MagickCore/memory.c double free and application crash) or possibly have unspecified other impact via a crafted file.

Apport does not properly handle crashes originating from a PID namespace allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion, possibly gain root privileges, or escape from containers. The issamens() function returns True when /proc/<global pid>/ does not exist in order to indicate that the crash should be handled in the global namespace rather than inside of a container. However, the portion of the data/apport code that decides whether or not to forward a crash to a container does not always replace sys.argv[1] with the value stored in the hostpid variable when /proc/<global pid>/ does not exist which results in the container pid being used in the global namespace. This flaw affects versions 2.20.8-0ubuntu4 through 2.20.9-0ubuntu7, 2.20.7-0ubuntu3.7, 2.20.7-0ubuntu3.8, 2.20.1-0ubuntu2.15 through 2.20.1-0ubuntu2.17, and 2.14.1-0ubuntu3.28.

ImageMagick 7.0.7-22 Q16 has memory leaks in the ReadDCMImage function in coders/dcm.c.

An issue was discovered in network-manager-applet (aka network-manager-gnome) in Ubuntu 12.04 LTS, 14.04 LTS, 16.04 LTS, and 16.10. A local attacker could use this issue at the default Ubuntu login screen to access local files and execute arbitrary commands as the lightdm user. The exploitation requires physical access to the locked computer and the Wi-Fi must be turned on. An access point that lets you use a certificate to login is required as well, but it's easy to create one. Then, it's possible to open a nautilus window and browse directories. One also can open some applications such as Firefox, which is useful for downloading malicious binaries.

It was discovered that MethodHandle did not properly handle variable argument lists when permuting or dropping arguments. An untrusted Java application or applet could possibly use this flaw to bypass Java sandbox restrictions.

It was discovered that the AlgorithmChecker and SignatureAndHashAlgorithm classes did not properly prevent the SIGNATUREPRIMITIVESET set from being modified. An untrusted Java application or applet could possibly use this flaw to alter the content of the SIGNATUREPRIMITIVESET set.

As per Upstream advisory:

A double free bug was discovered when OpenSSL parses malformed DSA private keys and could lead to a DoS attack or memory corruption for applications that receive DSA private keys from untrusted sources. This scenario is considered rare.

This issue affects OpenSSL versions 1.0.2 and 1.0.1.

OpenSSL 1.0.2 users should upgrade to 1.0.2g OpenSSL 1.0.1 users should upgrade to 1.0.1s

This issue was reported to OpenSSL on 7th February 2016 by Adam Langley (Google/BoringSSL) using libFuzzer. The fix was developed by Dr Stephen Henson of OpenSSL.

Unity before 7.2.1, as used in Ubuntu 14.04, does not properly restrict access to the Dash when the lock screen is active, which allows physically proximate attackers to bypass the lock screen and execute arbitrary commands, as demonstrated by pressing the SUPER key before the screen auto-locks.

Unity before 7.2.1, as used in Ubuntu 14.04, does not properly handle keyboard shortcuts, which allows physically proximate attackers to bypass the lock screen and execute arbitrary commands, as demonstrated by right-clicking on the indicator bar and then pressing the ALT and F2 keys.

A vulnerability was found in the libxml2 library. A heap-buffer-overflow could happen in xmlStrncat.

The gmp plugin in strongSwan before 5.5.3 does not properly validate RSA public keys before calling mpzpowmsec, which allows remote peers to cause a denial of service (floating point exception and process crash) via a crafted certificate.

json-c could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow and out-of-bounds write. By persuading a victim to run a specially crafted file, an attacker could exploit this vulnerability to execute arbitrary code on the system.

Apport reads and writes information on a crashed process to /proc/pid with elevated privileges. Apport then determines which user the crashed process belongs to by reading /proc/pid through getpidinfo() in data/apport. An unprivileged user could exploit this to read information about a privileged running process by exploiting PID recycling. This information could then be used to obtain ASLR offsets for a process with an existing memory corruption vulnerability. The initial fix introduced regressions in the Python Apport library due to a missing argument in Report.addprocenviron in apport/report.py. It also caused an autopkgtest failure when reading /proc/pid and with Python 2 compatibility by reading /proc maps. The initial and subsequent regression fixes are in 2.20.11-0ubuntu16, 2.20.11-0ubuntu8.6, 2.20.9-0ubuntu7.12, 2.20.1-0ubuntu2.22 and 2.14.1-0ubuntu3.29+esm3.

Race condition in Apport before 2.17.2-0ubuntu1.1 as packaged in Ubuntu 15.04, before 2.14.70ubuntu8.5 as packaged in Ubuntu 14.10, before 2.14.1-0ubuntu3.11 as packaged in Ubuntu 14.04 LTS, and before 2.0.1-0ubuntu17.9 as packaged in Ubuntu 12.04 LTS allow local users to write to arbitrary files and gain root privileges.

Apport 2.13 through 2.20.7 does not properly handle crashes originating from a PID namespace allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion or possibly gain root privileges, a different vulnerability than CVE-2017-14179.
