RedHat: lv privilege escalation vulnerability
Summary
Summary
Lv is a powerful file viewer similar to less. It can decode and encode multilingual streams through many coding systems, such as ISO-8859, ISO-2022, EUC, SJIS Big5, HZ, and Unicode. A bug has been found in versions of lv that read a .lv file in the current directory. Local attackers can use this to place an .lv file in any directory to which they have write access. Any user who subsequently runs lv in that directory and uses the v (edit) command can be forced to execute an arbitrary program. Users are advised to upgrade to these erratum packages, which contain a version of lv that is patched to read the .lv configuration file only in the user's home directory.
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.
