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.
Moxilla Firefox allows remote attackers to bypass the Same Origin Policy to read arbitrary files or gain privileges.
The VNC websocket frame decoder in QEMU allows remote attackers to cause a denial of service (memory and CPU consumption) via a large (1) websocket payload or (2) HTTP headers section.
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
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.
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.
