TITLE:
JHead "DoCommand()" Buffer Overflow Security Issue

SECUNIA ADVISORY ID:
SA32340

VERIFY ADVISORY:
http://secunia.com/advisories/32340/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
JHead 2.x
http://secunia.com/advisories/product/20202/

DESCRIPTION:
A security issue has been reported in JHead, which potentially can be
exploited by malicious, local users to gain escalated privileges.

The security issue is caused due to a boundary error within the
"DoCommand()" function in jhead.c. This can be exploited to cause a
stack-based buffer overflow by tricking a user into using the "-cmd"
argument to process a file having an overly long filename.

NOTE: Other similar security issues are reportedly also present.

This security issue is reported in versions prior to 2.84.

SOLUTION:
Update to version 2.84.

PROVIDED AND/OR DISCOVERED BY:
Reported by Marc Merlin and John Dong in an Ubuntu bug report.
