Package        : rxvt
Problem type   : buffer overflow
Debian-specific: no

Samuel Dralet reported on bugtraq that version 2.6.2 of rxvt (a
VT102 terminal emulator for X) have a buffer overflow in the
tt_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 him to modify the utmp file.

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