14 October 2005

curl, wget vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 5.10
  • Ubuntu 5.04
  • Ubuntu 4.10

Software Description

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
libcurl2
libcurl3
wget
Ubuntu 5.04
libcurl2
libcurl3
wget
Ubuntu 4.10
libcurl2
libcurl3
wget
