Debian Security Advisory DSA 706-1 security@debian.org

Package : axel
Vulnerability : buffer overflow
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2005-0390
BugTraq ID : 13059

Ulf Härnhammar from the Debian Security Audit Project discovered a buffer overflow in axel, a light download accellerator. When reading remote input the program did not check if a part of the input can overflow a buffer and maybe trigger the execution of arbitrary code.

For the stable distribution (woody) this problem has been fixed in version 1.0a-1woody1.

For the unstable distribution (sid) this problem has been fixed in version 1.0b-1.

We recommend that you upgrade your axel package.
