-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------ Debian Security Advisory DSA-2040-1 security@xxxxxxxxxx http://www.debian.org/security/ Sébastien Delafond May 02, 2010 http://www.debian.org/security/faq - ------------------------------------------------------------------------ Package : squidguard Vulnerability : buffer overflow Problem type : remote Debian-specific: no CVE Ids : CVE-2009-3700, CVE-2009-3826 Debian Bug : 553319 It was discovered that in squidguard, a URL redirector/filter/ACL plugin for squid, several problems in src/sgLog.c and src/sgDiv.c allow remote users to either: * cause a denial of service, by requesting long URLs containing many slashes; this forces the daemon into emergency mode, where it does not process requests anymore. * bypass rules by requesting URLs whose length is close to predefined buffer limits, in this case 2048 for squidguard and 4096 or 8192 for squid (depending on its version). For the stable distribution (lenny), this problem has been fixed in version 1.2.0-8.4+lenny1. For the unstable distribution (sid), this problem has been fixed in version 1.2.0-9. We recommend that you upgrade your squidguard 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. Debian GNU/Linux 5.0 alias lenny - -------------------------------- Stable updates are available for alpha, amd64, arm, armel, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.
