TITLE:
Adobe Reader for Linux Insecure Temporary Files

SECUNIA ADVISORY ID:
SA29229

VERIFY ADVISORY:
http://secunia.com/advisories/29229/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
Adobe Reader 8.x
http://secunia.com/product/12829/

DESCRIPTION:
A security issue has been reported in Adobe Reader, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.

The security issue is caused due to the insecure handling of
temporary files within the "acroread" script when processing the
"installCertificate" option. This can be exploited via symlink
attacks in combination with a race condition to overwrite or delete
arbitrary files with the privileges of the user running the program.

The security issue is reported in version 8.1.2. Other versions may
also be affected.

SOLUTION:
Restrict local access to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
Reported in a SUSE security update.
