3. Description:
Squid is a high-performance proxy caching server for Web clients,
supporting FTP, gopher, and HTTP data objects.
A flaw was found in the way squid manipulated HTTP headers for cached
objects stored in system memory. An attacker could use this flaw to cause a
squid child process to exit. This interrupted existing connections and made
proxy services unavailable. Note: the parent squid process started a new
child process, so this attack only resulted in a temporary denial of
service. (CVE-2008-1612)
Users of squid are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
