Ytterligare information:

Två överbelastningssårbarheter har upptäckts i squid och squid3, en webbproxy. Projektet Common Vulnerabilities and Exposures identifierar följande problem:

CVE-2009-2855
Bastian Blank upptäckte att det är möjligt att orsaka en överbelastning med hjälp av ett specialskriven autentiseringshuvud med särskilda kommaseparerare.
CVE-2010-0308
Tomas Hoger upptäckte att det är möjligt att orsaka en överbelastning med hjälp av ogiltigt DNS-paket med endast huvuden.

För den stabila utgåvan (Lenny) har dessa problem rättats i version 2.7.STABLE3-4.1lenny1 av squid-paketet och version 3.0.STABLE8-3+lenny3 av squid3-paketet .

För den gamla stabila utgåvan (Etch) har dessa problem rättats i version 2.6.5-6etch5 av squid-paketet och version 3.0.PRE5-5+etch2 av squid3-paketet .

För uttestningsutgåvan (Squeeze) och den instabila utgåvan (Sid) kommer dessa problem att rättas inom kort.

Vi rekommenderar att ni uppgraderar era squid/squid3-paket.
