openSUSE Security Update: Security update for libXfont ______________________________________________________________________________
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)
