Moxilla Firefox allows remote attackers to bypass the Same Origin Policy to read arbitrary files or gain privileges.
A flaw was found in the way pi to pi futex requeueing was handled.
A local unprivileged user can use this flaw to increase their privileges on the system.
The Content Security Policy (CSP) implementation in Mozilla Firefox before 27.0 and SeaMonkey before 2.24 operates on XSLT stylesheets according to style-src directives instead of script-src directives, which might allow remote attackers to execute arbitrary XSLT code by leveraging insufficient style-src restrictions.
A flaw was found in the way cifs handled iovecs with bogus pointers userland passed down via writev() during uncached writes.
An unprivileged local user with access to cifs share could use this flaw to crash the system or leak kernel memory. Privilege escalation cannot be ruled out (since memory corruption is involved), but is unlikely.
The default cache settings for cifs mounts on Red Hat Enterprise Linux prohibit successful exploitation of this issue.

Mozilla Firefox before 22.0, Firefox ESR 17.x before 17.0.7, Thunderbird before 17.0.7, and Thunderbird ESR 17.x before 17.0.7 do not properly handle onreadystatechange events in conjunction with page reloading, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted web site that triggers an attempt to execute data at an unmapped memory location.
It was discovered that libtasn1 library function asn1getbitder() could incorrectly report negative bit length of the value read from ASN.1 input. This could possibly lead to an out of bounds access in an application using libtasn1, for example in case if application tried to terminate read value with NUL byte.
The following upstream commit corrects the issue and causes the function to report error rather than return negative length value: http://git.savannah.gnu.org/cgit/libtasn1.git/commit/?id=1c3ccb3e040bf13e342ee60bc23b21b97b11923f
A flaw was found in the way Linux kernel's floppy driver treated userspace provided data in certain error code path while processing FDRAWCMD ioctl command. An local user with write access to /dev/fdX could use this flaw to kfree() arbitrary data. (CVE-2014-1737)
It was found that Linux kernel's floppy driver leaked internal kernel memory addresses to userspace during processing of FDRAWCMD ioctl command. An local user with write access to /dev/fdX could use this flaw to get information about kernel heap arrangment. (CVE-2014-1738)
An local user with write access to /dev/fdX could use these two flaws (CVE-2014-1737 in combination with CVE-2014-1738) to escalate their privileges on the system.

A denial of service flaw was found in the way the JRE processes XML. A remote attacker could use this flaw to supply crafted XML that would lead to a denial of service.
