Description:
Some vulnerabilities have been reported in zgv/xzgv, which potentially can be exploited by malicious people to compromise a vulnerable system.
The vulnerabilities are caused due to various integer overflows when processing images. These can be exploited to cause buffer overflows via images containing specially crafted headers.
Successful exploitation may allow execution of arbitrary code when a malicious image is viewed.
The vulnerabilities have been reported in zgv 5.8 and prior, and in xzgv 0.8 and prior.
