Affected Products:

______________________________________________________________________________

 

An update that fixes four vulnerabilities is now available.

 

Description:

 

 

This update for graphite2 fixes the following issues:

 

- CVE-2016-1521: The directrun function in directmachine.cpp in

Libgraphite did not validate a certain skip operation, which allowed

remote attackers to execute arbitrary code, obtain sensitive information,

or cause a denial of service (out-of-bounds read and application crash)

via a crafted Graphite smart font.

 

- CVE-2016-1522: Code.cpp in Libgraphite did not consider recursive load

calls during a size check, which allowed remote attackers to cause a

denial of service (heap-based buffer overflow) or possibly execute

arbitrary code via a crafted Graphite smart font.

 

- CVE-2016-1523: The SillMap::readFace function in FeatureMap.cpp in

Libgraphite mishandled a return value, which allowed remote attackers to

cause a denial of service (missing initialization, NULL pointer

dereference, and application crash) via a crafted Graphite smart font.

 

- CVE-2016-1526: The TtfUtil:LocaLookup function in TtfUtil.cpp in

Libgraphite incorrectly validated a size value, which allowed remote

attackers to obtain sensitive information or cause a denial of service

(out-of-bounds read and application crash) via a crafted Graphite smart

font.
