Package        : reprepro
Vulnerability  : authentication bypass
Problem-Type   : remote
Debian-specific: yes
CVE ID         : CVE-2007-4739
Debian Bug     : 440535

It was discovered that reprepro, a tool to create a repository of Debian packages, when updating from a remote site only checks for the validity of known signatures, 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.

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

For the unstable distribution (sid) this problem has been fixed in version 2.2.4-1.

We recommend that you upgrade your reprepro package.
