freetype vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 15.04
– Ubuntu 14.04 LTS
– Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in FreeType.
Software Description:
– freetype: FreeType 2 is a font engine library
Details:
It was discovered that FreeType did not correctly handle certain malformed
font files. If a user were tricked into using a specially crafted font
file, a remote attacker could cause FreeType to crash or hang, resulting in
a denial of service, or possibly expose uninitialized memory.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 15.04:
libfreetype6 2.5.2-2ubuntu3.1
Ubuntu 14.04 LTS:
libfreetype6 2.5.2-1ubuntu2.5
Ubuntu 12.04 LTS:
libfreetype6 2.4.8-1ubuntu2.3
After a standard system update you need to restart your session to make
all the necessary changes.
