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.
