Jakub Wilk discovered that clang's scan-build utility insecurely handled temporary files. A local attacker could use this flaw to perform a symbolic link attack against users running the scan-build utility.

The session-restore feature in Mozilla Firefox before 28.0 and SeaMonkey before 2.25 does not consider the Content Security Policy of a data: URL, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted document that is accessed after a browser restart.
The startauthentication function in lightdm-gtk-greeter.c in LightDM GTK+ Greeter before 1.7.1 does not properly handle the return value from the lightdmgreetergetauthenticationuser function, which allows local users to cause a denial of service (NULL pointer dereference) via an empty username.
Stack-based buffer overflow in socat 1.3.0.0 through 1.7.2.2 and 2.0.0-b1 through 2.0.0-b6 allows local users to cause a denial of service (segmentation fault) via a long server name in the PROXY-CONNECT address in the command line.
Percona XtraBackup before 2.1.6 uses a constant string for the initialization vector (IV), which makes it easier for local users to defeat cryptographic protection mechanisms and conduct plaintext attacks.
Bodo Möller, Thai Duong and Krzysztof Kotowicz of Google discovered a flaw in the design of SSL version 3.0 that would allow an attacker to calculate the plaintext of secure connections, allowing, for example, secure HTTP cookies to be stolen.

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.

Description of the problem:
Domblkstat is possible even with read-only connection, so whenever migration with spice is done and domblkstat gets called at the same time as qemuMonitorGetSpiceMigrationStatus(), there is certain possibility that the daemon crashes.
An unprivileged user able to issue commands to running libvirtd could use this flaw to crash libvirtd and prevent more privileged clients from working correctly.

An issue exists AccountService 0.6.37 in the userchangepasswordauthorizedcb() function in user.c which could let a local users obtain encrypted passwords.
The sd2parsersrcfork function in sd2.c in libsndfile allows attackers to have unspecified impact via vectors related to a (1) map offset or (2) rsrc marker, which triggers an out-of-bounds read.
The PEARREST class in REST.php in PEAR in PHP through 5.6.0 allows local users to write to arbitrary files via a symlink attack on a (1) rest.cachefile or (2) rest.cacheid file in /tmp/pear/cache/, related to the retrieveCacheFirst and useLocalCache functions.
