(RHSA-2005:068) less security update

The less utility is a text file browser that resembles more, but has
extended capabilities.

Victor Ashik discovered a heap based buffer overflow in less, caused by a
patch added to the less package in Red Hat Enterprise Linux 3. An attacker
could construct a carefully crafted file that could cause less to crash or
possibly execute arbitrary code when opened. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0086
to this issue. Note that this issue only affects the version of less
distributed with Red Hat Enterprise Linux 3.

Red Hat believes that the Exec-Shield technology (enabled by default since
Update 3) will block attempts to remotely exploit this vulnerability on x86
architectures.

All users of the less package should upgrade to this updated package,
which resolves this issue.
