Vigil@nce: imlib2, several vulnerabilities
October 2008 by Vigil@nce
An attacker can create a malicious image leading to code execution when it is displayed by imlib2.
Consequences: user access/rights, denial of service of client
Means of attack: no proof of concept, no attack
Ability of attacker: expert (4/4)
Confidence: confirmed by the editor (5/5)
Diffusion of the vulnerable configuration: high (3/3)

The imlib2 library handles the display and the conversion of images. It has several vulnerabilities.
An ARGB (Alpha/Red/Green/Blue) image can create a denial of service. [grav:1/4]
A JPEG image can create a denial of service. [grav:1/4]
A TGA image can create a buffer overflow. [grav:2/4]
A XPM image can create a buffer overflow. [grav:2/4]
An attacker can therefore create a malicious image leading to a denial of service or to code execution in applications linked to imlib2.
