Summary
Red Hat Security Advisory: sharutils security update
Notes
Topic
Updated packages for sharutils which fix potential privilege escalation
using the uudecode utility are available.
Details
The sharutils package contains a set of tools for encoding and decoding
packages of files in binary or text format.
The uudecode utility creates an output file without checking to see if
it was about to write to a symlink or a pipe. If a user uses uudecode to
extract data into open shared directories, such as /tmp, this vulnerability
could be used by a local attacker to overwrite files or lead to privilege
escalation. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2002-0178 to this issue.
Users are advised to upgrade to these errata packages, which
contain a patch that resolves this issue.

"details": "Before applying this update, make sure all previously released errata\nrelevant to your system have been applied.\n\nTo update all RPMs for your particular architecture, run:\n\nrpm -Fvh [filenames]\n\nwhere [filenames] is a list of the RPMs you wish to upgrade. 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.",
