Debian Security Advisory

DSA-082-1 xvt -- Buffer Overflow

Date Reported:

18 Oct 2001

Affected Packages:

xvt

Vulnerable:

Yes

Security database references:

In the Bugtraq database (at SecurityFocus): BugTraq ID 2964.
In Mitre's CVE dictionary: CVE-2001-1561.

More information:

Christophe Bailleux reported on bugtraq that Xvt is vulnerable to a buffer overflow in its argument handling. Since Xvt is installed setuid root, it was possible for a normal user to pass carefully-crafted arguments to xvt so that xvt executed a root shell.

This problem has been fixed by the maintainer in version 2.1-13 of xvt for Debian unstable and 2.1-13.0potato.1 for the stable Debian GNU/Linux 2.2.

We recommend that you upgrade your xvt package immediately.

Fixed in:

Debian GNU/Linux 2.2 (potato)
