249a8c42-6973-11d9-ae49-000c41e2cdad	zgv -- exploitable heap overflows infamous41md reports: zgv uses malloc() frequently to allocate memory for storing image data. When calculating how much to allocate, user supplied data from image headers is multiplied and/or added without any checks for arithmetic overflows. We can overflow numerous calculations, and cause small buffers to be allocated. Then we can overflow the buffer, and eventually execute code. There are a total of 11 overflows that are exploitable to execute arbitrary code. These bugs exist in both zgv and xzgv.

zgv, xzgv -- heap overflow vulnerability

Gentoo reports:

Andrea Barisani of Gentoo Linux discovered xzgv and zgv allocate insufficient memory when rendering images with more than 3 output components, such as images using the YCCK or CMYK colour space. When xzgv or zgv attempt to render the image, data from the image overruns a heap allocated buffer.

An attacker may be able to construct a malicious image that executes arbitrary code with the permissions of the xzgv or zgv user when attempting to render the image.
