SciLinux: CVE-2009-2855 Low: squid SL5.x i386/x86_64
Summary
remote attacker could issue a crafted request to the Squid server,causing excessive CPU use (up to 100%). (CVE-2009-2855)Note: The CVE-2009-2855 issue only affected non-default configurationsthat use an external ACL helper script.A flaw was found in the way Squid handled truncated DNS replies. Aremote attacker able to send specially-crafted UDP packets to Squid'sDNS client port could trigger an assertion failure in Squid's childprocess, causing that child process to exit. (CVE-2010-0308)This update also fixes the following bugs:* Squid's init script returns a non-zero value when trying to stop astopped service. This is not LSB compliant and can generate difficultiesin cluster environments. This update makes stopping LSB compliant.(BZ#521926)* Squid is not currently built to support MAC address filtering in ACLs.This update includes support for MAC address filtering. (BZ#496170)* Squid is not currently built to support Kerberos negotiateauthentication. This update enables Kerberos authentication. (BZ#516245)* Squid does not include the port number as part of URIs it constructswhen configured as an accelerator. This results in a 403 error. Thisupdate corrects this behavior. (BZ#538738)* the error_map feature does not work if the same handling is set alsoon the HTTP server that operates in deflate mode. This update fixes thisissue. (BZ#470843)After installing this update, the squid service will be restartedautomatically.SL 5.xSRPMS:squid-2.6.STABLE21-6.el5.src.rpmi386:squid-2.6.STABLE21-6.el5.i386.rpmx86_64:squid-2.6.STABLE21-6.el5.x86_64.rpm-Connie Sieh-Troy Dawson
