Debian DSA-062-1 : rxvt - buffer overflow

medium Nessus Plugin ID 14899

Synopsis

The remote Debian host is missing a security-related update.

Description

Samuel Dralet reported on bugtraq that version 2.6.2 of rxvt (a VT102 terminal emulator for X) have a buffer overflow in thett_printf() function. A local user could abuse this making rxvt print a special string using that function, for example by using the -T or -name command-line options. That string would cause a stack overflow and contain code which rxvt will execute.

Since rxvt is installed sgid utmp an attacker could use this to gain utmp which would allow them to modify the utmp file.

Solution

This has been fixed in version 2.6.2-2.1, and we recommend that you upgrade your rxvt package.
