Debian DSA-1394-1 : reprepro - authentication bypass

medium Nessus Plugin ID 27549

Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that reprepro, a tool to create a repository of Debian packages, only checks the validity of known signatures when updating from a remote site, and thus does not reject packages with only unknown signatures. This allows an attacker to bypass this authentication mechanism.

The oldstable distribution (sarge) is not affected by this problem.

Solution

Upgrade the reprepro package.

For the stable distribution (etch) this problem has been fixed in version 1.3.1+1-1.
