"Squid is a high-performance proxy caching server for web clients,
supporting FTP, Gopher, and HTTP data objects.

It was found that string comparison functions in Squid did not
properly handle the comparisons of NULL and empty strings. A remote,
trusted web client could use this flaw to cause the squid daemon to
crash via a specially crafted request. (CVE-2010-3072)

This update also fixes the following bugs :

  - A small memory leak in Squid caused multiple 'ctx: enter
    level' messages to be logged to
    '/var/log/squid/cache.log'. This update resolves the
    memory leak. (BZ#666533)

  - This erratum upgrades Squid to upstream version 3.1.10.
    This upgraded version supports the Google Instant
    service and introduces various code improvements.
    (BZ#639365)

Users of squid should upgrade to this updated package, which resolves
these issues. After installing this update, the squid service will be
restarted automatically."
