Detail

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog) Ubuntu 5.04 (Hoary Hedgehog) Ubuntu 5.10 (Breezy Badger)

The following packages are affected:

libcurl2 libcurl3 wget

The problem can be corrected by upgrading the affected package to the following versions:

Ubuntu 4.10:
libcurl2 7.12.0.is.7.11.2-1ubuntu0.2

Ubuntu 5.04:
libcurl2 1:7.11.2-12ubuntu3.2
libcurl3 7.12.3-2ubuntu3.2

Ubuntu 5.10:
libcurl3 7.14.0-2ubuntu1.1
wget 1.10-2ubuntu0.1
In general, a standard system upgrade is sufficient to effect the necessary changes. However, if you have the Apache web server installed, you need to restart it with

sudo /etc/init.d/apache2 restart

to make sure that Apache uses the updated Curl library.

Details follow:

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.

Id Description
20012 cURL/libcURL NTLM Username ntlm_output() Function Overflow
20011 GNU wget NTLM Username ntlm_output() Function Overflow

A remote overflow exists in wget. The 'ntlm_output()' function fails to perform proper bounds checking resulting in a buffer overflow. With a specially crafted HTTP redirect request containing an overly long NTLM username, a remote attacker can cause arbitrary code execution resulting in a loss of integrity.
