Summary :

These remote packages are missing security patches :
- squid
- squid-cgi
- squid-common
- squidclient


Description :

A possible authentication bypass was discovered in the LDAP
authentication backend. LDAP ignores leading and trailing whitespace
in search filters. This could possibly be abused to bypass explicit
access controls or confuse accounting when using several variants of

- squid-common-2.5.5-6ubuntu0.4 (Ubuntu 4.10)
- squidclient-2.5.5-6ubuntu0.4 (Ubuntu 4.10)
