A race condition was found in the way Linux kernel's memory subsystem handled breakage of the read only private mappings COW situation on write access.
An unprivileged local user could use this flaw to gain write access to otherwise read only memory mappings and thus increase their privileges on the system.
Red Hat is aware of this issue and if you have questions about the affectedness of your system please contact Red Hat Support. For additional information see https://access.redhat.com/security/vulnerabilities/2706661
Use-after-free vulnerability in the ByteArray class in the ActionScript 3 (AS3) implementation in Adobe Flash Player 13.x through 13.0.0.296 and 14.x through 18.0.0.194 on Windows and OS X and 11.x through 11.2.202.468 on Linux allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted Flash content that overrides a valueOf function, as exploited in the wild in July 2015.
Adobe Security Bulletin APSB15-14 for Adobe Flash Player describes a flaw that can possibly lead to code execution when Flash Player is used to play a specially crafted SWF file.
Quoting from the APSB15-14:
Adobe has released security updates for Adobe Flash Player for Windows, Macintosh and Linux. These updates address a critical vulnerability (CVE-2015-3113) that could potentially allow an attacker to take control of the affected system.
Adobe is aware of reports that CVE-2015-3113 is being actively exploited in the wild via limited, targeted attacks. Systems running Internet Explorer for Windows 7 and below, as well as Firefox on Windows XP, are known targets.

Adobe Flash Player before 13.0.0.281 and 14.x through 17.x before 17.0.0.169 on Windows and OS X and before 11.2.202.457 on Linux allows attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, as exploited in the wild in April 2015, a different vulnerability than CVE-2015-0347, CVE-2015-0350, CVE-2015-0352, CVE-2015-0353, CVE-2015-0354, CVE-2015-0355, CVE-2015-0360, CVE-2015-3038, CVE-2015-3041, and CVE-2015-3042.
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.
It was discovered that the Invariance Weakness of the RC4 stream cipher could be used to recover plaintext from a TLS connection, when RC4 encryption is used.
"The Invariance Weakness is an L-shape key pattern in RC4 keys, which once it exists in an RC4 key, preserves part of the state permutation intact throughout the initialization process. This intact part includes the least significant bits of the permutation, when processed by the PRGA algorithm, determines the least significant bits of the allegedly pseudo-random output stream along a long prefix of the stream."
This can lead to significant leakage of plaintext bytes from the ciphertext.

GStreamer before 1.4.5, as used in Mozilla Firefox before 38.0, Firefox ESR 31.x before 31.7, and Thunderbird before 31.7 on Linux, allows remote attackers to cause a denial of service (buffer over-read and application crash) or possibly execute arbitrary code via crafted H.264 video data in an m4v file.
