The remote host is affected by the vulnerability described in GLSA-200604-10 (zgv, xzgv: Heap overflow)
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.
Impact :
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.
Workaround :
There is no known workaround at this time.
