Gentoo Linux Security Advisory GLSA 200604-10 - 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. Versions less than 0.8-r2 are affected.
