Summary
Red Hat Security Advisory: fetchmail security update

Notes

Topic
Updated Fetchmail packages are available for Red Hat Linux Advanced Server which close a remotely-exploitable vulnerability in unpatched versions of Fetchmail prior to 6.2.0. [Updated 06 Feb 2003] Added fixed packages for Advanced Workstation
Details
Fetchmail is a remote mail retrieval and forwarding utility intended for use over on-demand TCP/IP links such as SLIP and PPP connections. A bug has been found in the header parsing code in versions of Fetchmail prior to 6.2.0. The bug allows a remote attacker to crash Fetchmail and potentially execute arbitrary code by sending a carefully crafted email which is parsed by Fetchmail. All users of Fetchmail are advised to upgrade to the errata packages containing a backported fix which corrects this issue.

Only those\nRPMs which are currently installed will be updated.  Those RPMs which are\nnot installed but included in the list will not be updated.  Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains the\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network.  Many\npeople find this an easier way to apply updates.  To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.",
