Debian DSA-874-1 : lynx - buffer overflow

high Nessus Plugin ID 22740

Synopsis

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

Description

Ulf Harnhammar discovered a buffer overflow in lynx, a text-mode browser for the WWW that can be remotely exploited. During the handling of Asian characters when connecting to an NNTP server lynx can be tricked to write past the boundary of a buffer which can lead to the execution of arbitrary code.

Solution

Upgrade the lynx package.

For the old stable distribution (woody) this problem has been fixed in version 2.8.4.1b-3.3.

For the stable distribution (sarge) this problem has been fixed in version 2.8.5-2sarge1.
