Yderligere oplysninger:

Flere sårbarheder er opdaget i Squid, cache-programmet til Internet-objekter og den populære WWW-proxycache. Projektet Common Vulnerabilities and Exposures har fundet frem til følgende sårbarheder:

CAN-2005-0173
LDAP er meget eftergivende med hensyn til mellemrum i søgefiltre, og det kunne udnyttes til logge på ved hjælp af flere variationer af login-navnet, og dermed muligvis omgå eksplicitte adgangskontroller eller forvirre kontoadministrationen.
CAN-2005-0175
Man har opdaget cache-forurening/forgiftning via opsplittede HTTP-svar..
CAN-2005-0194
Adgangskontrollernes betydning bliver noget forvirrende, hvis en eller flere af de refererede ACL'er (adgangskontrollister) er tomme, uden nogen medlemmer.
CAN-2005-0211
Længdeargumentet i WCCP recvfrom()-kaldet er større end det bør være. En angriber kunne sende WCCP-pakke, der er større end normalt, hvilket kunne få en buffer til at løbe over.

I den stabile distribution (woody) er disse problemer rettet i version 2.4.6-2woody6.

I den ustabile distribution (sid) er disse problemer rettet i version 2.5.7-7.

Vi anbefaler at du opgraderer din squid-pakke.
