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.
(CVE-2006-6169)
All users of GnuPG are advised to upgrade to this updated package, which contains a backported patch to correct these issues.
