RHSA-2005-068: less Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the less packages

Detailed Explanation for this Vulnerability Test

An updated less package that fixes segmentation fault when viewing binary
files is now available.

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. A possible hacker
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 ( has assigned the name CVE-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

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