Gentoo Linux Security Advisory GLSA 200504-09

Severity: Normal
Title: Axel: Vulnerability in HTTP redirection handling
Date: April 12, 2005
Bugs: #88264
ID: 200504-09


A buffer overflow vulnerability has been found in Axel which could lead to the execution of arbitrary code.


Axel is a console-based FTP/HTTP download accelerator.

Affected packages

     Package        /  Vulnerable  /                        Unaffected

  1  net-misc/axel       < 1.0b                                >= 1.0b


A possible buffer overflow has been reported in the HTTP redirection handling code in conn.c.


A remote attacker could exploit this vulnerability by setting up a malicious site and enticing a user to connect to it. This could possibly lead to the execution of arbitrary code with the permissions of the user running Axel.


There is no known workaround at this time.


All Axel users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-misc/axel-1.0b"
