Announcement ID: openSUSE-SU-2015:0614-1

Rating: important

References: #921978

Cross-References: CVE-2015-1802 CVE-2015-1803 CVE-2015-1804

 

Affected Products:

openSUSE 13.2

openSUSE 13.1

______________________________________________________________________________

 

An update that fixes three vulnerabilities is now available.

 

Description:

 

libXFont was updated to fix three vulnerabilities when parsing BDF files

(bnc#921978)

 

As libXfont is used by the X server to read font files, and an

unprivileged user with access to the X server can tell the X server to

read a given font file from a path of their choosing, these

vulnerabilities have the potential to allow unprivileged users to run code

with the privileges of the X server.

 

The following vulnerabilities were fixed:

* The BDF parser could allocate the a wrong buffer size, leading to out of

bound writes (CVE-2015-1802)

* The BDF parser could crash when trying to read an invalid pointer

(CVE-2015-1803)

* The BDF parser could read 32 bit metrics values into 16 bit integers,

causing an out-of-bound memory access though integer overflow

(CVE-2015-1804)
