Security Advisory Updated man package fixing GID security problems.

Advisory: RHSA-2001:072-14
Type: Security Advisory
Severity: N/A
Issued on: 2001-05-28
Last updated on: 2001-09-06
Affected Products: Red Hat Linux 6.2
Red Hat Linux 7.0
Red Hat Linux 7.1
CVEs (cve.mitre.org): CVE-2001-1028
CVE-2001-1227

Details

Updated man packages fixing a local GID man exploit and a
potential GID man to root exploit, as well as a problem with the
man paths of Red Hat Linux 5.x and 6.x.

Users could gain access to the GID man by overrunning a buffer in the
ultimate_source() function.

Users with GID man could get root access by creating man pages with
filenames containing escape characters.

Furthermore, the previous errata package hardcoded Red Hat Linux 7.x man
paths even on Red Hat Linux 5.x and 6.x.


Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains
the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. 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.
