3. Description:

 

Foomatic is a comprehensive, spooler-independent database of printers,

printer drivers, and driver descriptions. The package also includes

spooler-independent command line interfaces to manipulate queues and to

print files and manipulate print jobs.

 

It was discovered that the unhtmlify() function of foomatic-rip did not

correctly calculate buffer sizes, possibly leading to a heap-based memory

corruption. A malicious attacker could exploit this flaw to cause

foomatic-rip to crash or, possibly, execute arbitrary code.

(CVE-2010-5325)

 

It was discovered that foomatic-rip failed to remove all shell special

characters from inputs used to construct command lines for external

programs run by the filter. An attacker could possibly use this flaw to

execute arbitrary commands. (CVE-2015-8327, CVE-2015-8560)

 

All foomatic users should upgrade to this updated package, which contains

backported patches to correct these issues.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.
