Multiple vulnerabilities has been found and corrected in squid :
Due to incorrect buffer limits and related bound checks Squid is vulnerable to a denial of service attack when processing specially crafted requests or responses (CVE-2009-2621).
Due to incorrect data validation Squid is vulnerable to a denial of service attack when processing specially crafted responses (CVE-2009-2622).
This update provides fixes for these vulnerabilities.
Update :
Additional upstream security patches were applied :
Debug warnings fills up the logs.
