TITLE:
libpcd PhotoCD Image Error Handling Buffer Overflow Vulnerabilities
SECUNIA ADVISORY ID:
SA11690
VERIFY ADVISORY:
http://secunia.com/advisories/11690/
CRITICAL:
Less critical
IMPACT:
Privilege escalation
WHERE:
Local system
SOFTWARE:
xpcd 2.x
libpcd 1.0.x
DESCRIPTION:
Jaguar has reported some vulnerabilities in libpcd, which potentially
can be exploited by malicious people to execute arbitrary code on a
user's system.
The vulnerabilities are caused due to three boundary errors within
the "pcd_open()" function during creation of certain error messages
when attempting to decode a PhotoCD image. These can be exploited to
cause buffer overflows if an overly long, specially crafted filename
is supplied.
Successful exploitation requires that a user is tricked into opening
a specially crafted PhotoCD image with a malicious filename.
The vulnerabilities have been reported in xpcd 2.08 and libpcd 1.0.1.
Other versions may also be affected.
SOLUTION:
Don't open untrusted PhotoCD images.
Use another product.
PROVIDED AND/OR DISCOVERED BY:
Jaguar
