RHEL 2.1 / 3 / 4 : gnupg (RHSA-2006:0754)

Critical Nessus Plugin ID 23798


The remote Red Hat host is missing a security update.


Updated GnuPG packages that fix two security issues are 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 discovered a stack overwrite flaw in the way GnuPG decrypts messages. An attacker could create carefully crafted message that could cause GnuPG to execute arbitrary code if a victim attempts to decrypt the message. (CVE-2006-6235)

A heap based buffer overflow flaw was found in the way GnuPG constructs messages to be written to the terminal during an interactive session. An attacker could create a carefully crafted message which with user interaction could cause GnuPG to execute arbitrary code with the permissions of the user running GnuPG.

All users of GnuPG are advised to upgrade to this updated package, which contains a backported patch to correct these issues.


Update the affected gnupg package.
