Test ID:1.3.6.1.4.1.25623.1.0.703062
Category:Debian Local Security Checks
Title:Debian: Security Advisory (DSA-3062-1)
Summary:The remote host is missing an update for the Debian 'wget' package(s) announced via the DSA-3062-1 advisory.
Description:Summary:
The remote host is missing an update for the Debian 'wget' package(s) announced via the DSA-3062-1 advisory.

Vulnerability Insight:
HD Moore of Rapid7 discovered a symlink attack in Wget, a command-line utility to retrieve files via HTTP, HTTPS, and FTP. The vulnerability allows to create arbitrary files on the user's system when Wget runs in recursive mode against a malicious FTP server. Arbitrary file creation may override content of user's files or permit remote code execution with the user privilege.

This update changes the default setting in Wget such that it no longer creates local symbolic links, but rather traverses them and retrieves the pointed-to file in such a retrieval.

For the stable distribution (wheezy), this problem has been fixed in version 1.13.4-3+deb7u2.

For the unstable distribution (sid), this problem has been fixed in version 1.16-1.

We recommend that you upgrade your wget packages.

Affected Software/OS:
'wget' package(s) on Debian 7.

Solution:
Please install the updated package(s).
