CVE-2004-1440  (opens in a new tab)

How to fix?

Upgrade Debian:unstable putty to version 0.56-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream putty package and not the putty package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Multiple heap-based buffer overflows in the modpow function in PuTTY before 0.55 allow (1) remote attackers to execute arbitrary code via an SSH2 packet with a base argument that is larger than the mod argument, which causes the modpow function to write memory before the beginning of its buffer, and (2) remote malicious servers to cause a denial of service (client crash) and possibly execute arbitrary code via a large bignum during authentication.
