An updated GnuPG package that fixes signature verification flaws as well as minor bugs is now available. This update has been rated as having important security impact by the Red Hat Security Response Team. GnuPG is a utility for encrypting data and creating digital signatures. Tavis Ormandy...

FreeBSD : gnupg -- false positive signature verification (63fe4189-9f97-11da-ac32-0001020eed82)

Werner Koch reports : The Gentoo project identified a security related bug in GnuPG. When using any current version of GnuPG for unattended signature verification e.g. by scripts and mail programs, false positive signature verification of detached signatures may occur. This problem affects the to...

USN-264-1: gnupg vulnerability

Tavis Ormandy discovered a flaw in gnupg's signature verification. In some cases, certain invalid signature formats could cause gpg to report a 'good signature' result for auxiliary unsigned data which was prepended or appended to the checked message part...

security flaw

gpgv in GnuPG before 1.4.2.1, when using unattended signature verification, returns a 0 exit code in certain cases even when the detached signature file does not carry a signature, which could cause programs that use gpgv to assume that the signature verification has succeeded. Note: this also...

Fedora Core 4 : gnupg-1.4.2.2-1 (2006-147)

Tavis Ormandy discovered a flaw in the way GnuPG verifies cryptographically signed data with inline signatures. It is possible for an attacker to add unsigned text to a signed message in such a way so that when the signed text is extracted, the unsigned text is extracted as well, appearing as if ...

CVE-2006-0049

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...

CVE-2006-0049

GnuPG (gnupg) prior to 1.4.2.2 is affected by CVE-2006-0049: it does not properly verify non-detached or inline signatures, allowing an attacker to inject unsigned data into a checked message and have the signature appear valid. Several advisories (Ubuntu USN-264-1, CentOS/CESA-2006:0266, Mandrak...

GLSA-200603-08 : GnuPG: Incorrect signature verification

The remote host is affected by the vulnerability described in GLSA-200603-08 GnuPG: Incorrect signature verification OpenPGP is the standard that defines the format of digital signatures supported by GnuPG. OpenPGP signatures consist of multiple sections, in a strictly defined order. Tavis Ormand...

Ubuntu 4.10 / 5.04 / 5.10 : gnupg vulnerability (USN-252-1)

Tavis Ormandy discovered a potential weakness in the signature verification of gnupg. gpgv and gpg --verify returned a successful exit code even if the checked file did not have any signature at all. The recommended way of checking the result is to evaluate the status messages, but some third-par...

GnuPG does not detect injection of unsigned data

Werner Koch reports: In the aftermath of the false positive signature verfication bug announced 2006-02-15 more thorough testing of the fix has been done and another vulnerability has been detected. This new problem affects the use of gpg for verification of signatures which are not detached...

GnuPG: Incorrect signature verification

Background GnuPG The GNU Privacy Guard is a free replacement for PGP Pretty Good Privacy. As GnuPG does not rely on any patented algorithms, it can be used without any restrictions. gpgv is the OpenPGP signature verification tool provided by the GnuPG system.
