## What is CVE-2009-3546?

CVE-2009-3546 is a critical memory corruption vulnerability in Php Php, published on 19 Oct 2009. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The _gdGetColors function in gd_gd.c in PHP 5.2.11 and 5.3.x before 5.3.1, and the GD Graphics Library 2.x, does not properly verify a certain colorsTotal structure member, which might allow remote attackers to conduct buffer overflow or buffer over-read attacks via a crafted GD file, a different vulnerability than CVE-2009-3293. NOTE: some of these details are obtained from third party information.

Weakness: CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer)
