Detailsinfo

A vulnerability was found in GnuPG up to 1.4.2.1. It has been declared as critical. Affected by this vulnerability is an unknown code block of the component Signed File Handler. As an impact it is known to affect integrity. The summary by CVE is:

gpg in GnuPG before 1.4.2.2 does not properly verify non-detached signatures, which allows attackers to inject unsigned data via a data packet that is not associated with a control packet, which causes the check for concatenated signatures to report that the signature is valid, a different vulnerability than CVE-2006-0455.

The bug was discovered 03/09/2006. The weakness was disclosed 03/10/2006 by Tavis Ormandy (Website). The advisory is shared at lists.gnupg.org. This vulnerability is known as CVE-2006-0049 since 12/28/2005. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 21098 (Mandrake Linux Security Advisory : gnupg (MDKSA-2006:055)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 117739 (CentOS Security Update for GnuPG (CESA-2006:0266)).

Upgrading to version 1.4.2.2 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at gnupg.org.
