Detail
| Problem Description: 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 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. 5.
