Package : mozilla-firefox
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE IDs : CVE-2006-4310 CVE-2006-5462 CVE-2006-5463 CVE-2006-5464

This update covers packages for the little endian MIPS architecture
missing in the original advisory.

Several security related problems have been discovered in Mozilla and
derived products such as Mozilla Firefox. The Common Vulnerabilities
and Exposures project identifies the following vulnerabilities:

CVE-2006-4310

Tomas Kempinsky discovered that malformed FTP server responses
could lead to denial of service.

CVE-2006-5462

Ulrich Kühn discovered that the correction for a cryptographic
flaw in the handling of PKCS-1 certificates was incomplete, which
allows the forgery of certificates.

CVE-2006-5463

"shutdown" discovered that modification of JavaScript objects
during execution could lead to the execution of arbitrary
JavaScript bytecode.

CVE-2006-5464

Jesse Ruderman and Martijn Wargers discovered several crashes in
the layout engine, which might also allow execution of arbitrary
code.

CVE-2006-5748

Igor Bukanov and Jesse Ruderman discovered several crashes in the
JavaScript engine, which might allow execution of arbitrary code.

This update also adresses several crashes, which could be triggered by
malicious websites and fixes a regression introduced in the previous
Mozilla update.


For the stable distribution (sarge) these problems have been fixed in
version 1.0.4-2sarge13.

For the unstable distribution (sid) these problems have been fixed in
the current iceweasel package 2.0+dfsg-1.

We recommend that you upgrade your mozilla-firefox package.
