CVE-2013-4115

Buffer overflow in the idnsALookup function in dns_internal.cc in Squid 3.2 through 3.2.11 and 3.3 through 3.3.6 allows remote attackers to cause a denial of service (memory corruption and server termination) via a long name in a DNS lookup request.

Due to incorrect data validation Squid is vulnerable to a buffer overflow attack when processing specially crafted HTTP requests. This problem allows any trusted client or client script who can generate HTTP requests to trigger a buffer overflow in Squid, resulting in a termination of the Squid service (CVE-2013-4115).

Due to incorrect data validation Squid is vulnerable to a denial of service attack when processing specially crafted HTTP requests. This problem allows any client who can generate HTTP requests to perform a denial of service attack on the Squid service (CVE-2013-4123).

Also, due to being renamed in Squid 3.2, the Squid external acl helpers for matching against IP addresses and LDAP groups were not selected to be built in the squid package for Mageia 3.

This has been corrected and these helpers are now included. Additionally, the helpers for eDirectory IP address lookups and matching LDAP groups using Kerberos credentials have also been included.
