The Common Vulnerabilities and Exposures project identifies the following vulnerabilities: CAN-2005-0173 LDAP is very forgiving about spaces in search filters and this could be abused to log in using several variants of the login name, possibly bypassing explicit access controls or confusing accounting. CAN-2005-0175 Cache pollution/poisening via HTTP response splitting has been discovered. CAN-2005-0194 The meaning of the access controls becomes somewhat confusing if any of the referenced ACLs (access control lists) is declared empty, without any members. CAN-2005-0211 The length argument of the WCCP recvfrom() call is larger than it should be. An attacker may send a larger than normal WCCP packet that could overflow a buffer. For the stable distribution (woody) these problems have been fixed in version 2.4.6-2woody6. For the unstable distribution (sid) these problems have been fixed in version 2.5.7-7. We recommend that you upgrade your squid package. Upgrade Instructions - - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
