USN-205-1: Curl and wget vulnerabilities

14 October 2005

Curl and wget vulnerabilities

Releases

Details

A buffer overflow has been found in the NTLM authentication handler of
the Curl library and wget. By tricking an user or automatic system
that uses the Curl library, the curl application, or wget into
visiting a specially-crafted web site, a remote attacker could exploit
this to execute arbitrary code with the privileges of the calling
user.

The Ubuntu 4.10 and 5.04 versions of wget are not affected by this.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 5.10
  • wget -
  • libcurl3 -
  • libcurl2 -
Ubuntu 5.04
  • wget -
  • libcurl3 -
  • libcurl2 -
Ubuntu 4.10
  • wget -
  • libcurl3 -
  • libcurl2 -

In general, a standard system update will make all the necessary changes.
