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.
