Description
===========

- CVE-2015-2708 (Memory safety bugs fixed in Firefox ESR 31.7 and
Firefox 38):

Jesse Ruderman, Mats Palmgren, Byron Campen, and Steve Fink reported
memory safety problems and crashes that affect Firefox ESR 31.6 and

- CVE-2015-2710 (Buffer overflow with SVG content and CSS):

Using the Address Sanitizer tool, security researcher Atte Kettunen
found a buffer overflow during the rendering of SVG format graphics when
combined with specific CSS properties on a page. This results in a
potentially exploitable crash.

- CVE-2015-2713 (Use-after-free during text processing with vertical
text enabled):

Security researcher Scott Bell used the Address Sanitizer tool to
discover a use-after-free error during the processing of text when
vertical text is enabled. This leads to a potentially exploitable crash.

- CVE-2015-2716 (Buffer overflow when parsing compressed XML):

Security researcher Ucha Gobejishvili used the Address Sanitizer tool to
find a buffer overflow while parsing compressed XML content. This was
due to an error in how buffer space is created and modified when
handling large amounts of XML data. This results in a potentially
exploitable crash.


Impact

current user.
