TITLE:
Acon Multiple Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA29909

VERIFY ADVISORY:
http://secunia.com/advisories/29909/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
Acon 1.x
http://secunia.com/product/18431/

DESCRIPTION:
Some vulnerabilities have been reported in Acon, which can be
exploited by malicious, local users to gain escalated privileges.

The vulnerabilities are caused due to multiple boundary errors in
acon.c, menu.c, and child.c. These can be exploited to cause
stack-based buffer overflows in the "acon" setuid root binary via
e.g. an overly large $HOME environment variable or an overly large
number of terminal columns.

NOTE: Other boundary errors may also be present.

The vulnerabilities are reported in version 1.0.5. Other versions may
also be affected.

SOLUTION:
Restrict local access to trusted users only.

Use another product.

PROVIDED AND/OR DISCOVERED BY:
Reported by brian m. carlson and Helmut Grohne via the Debian bug
tracking system.
