Subject: CVE-2007-0855: Stack-based buffer overflow in Unrar

Date: Sun, 11 Feb 2007 22:05:22 +0100

Package: unrar
Version: 1:3.7.2-1
Severity: critical
Tags: security



>From CVE-2007-0855:

"Stack-based buffer overflow in RARLabs Unrar, as packaged in WinRAR and
possibly other products, allows user-assisted remote attackers to execute
arbitrary code via a crafted, password-protected archive."

See [1] for details. On the day of the public release of the advisory, unrar
3.7.3 has been released, which implies that version 3.7.2 is vulnerable (there
is no detailed changelog, however).

A new rar version has also been released.

Severity critical because rar or unrar is called by amavisd-new in its default
configuration (with parameter -p- to suppress password input), which probably
turns this issue into a remote arbitrary code execution vulnerability.

thanks

According to http://security-tracker.debian.net/tracker/CVE-2007-0855
unrar in sarge and etch is vulnerable
As I understand, no updates by security team are done to nonfree 
packages. But could update put into point release?

Unrar-nonfree is still vulnerable after last etch update. Maybe somebody
should upload fixed version finally?

An upload (based on the stable/oldstable version instead of a backport)
is being prepared, the only remaining issue is how we will build it on
all affected architectures.
