3. Problem description:
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.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
