Technical details
The vulnerability is an uninitialized memory read in the TGA image decoder (coders/tga.c) caused by insufficient initialization of local variables before use. An attacker can trigger this by providing a malformed TGA image to be processed, causing the decoder to leak uninitialized stack or heap memory. No special privileges or user interaction beyond image processing is required; the attack vector is network-based if the application processes untrusted image uploads.
Affected products
