What is CVE-2017-6312?

An integer overflow vulnerability in the io-ico.c component of gdk-pixbuf can be exploited by context-dependent attackers. By supplying a specially crafted ICO file with a malicious image entry offset, an attacker can trigger an out-of-bounds read, resulting in a segmentation fault and application crash. This issue is linked to specific compiler optimizations and requires careful handling of input to avoid denial of service.
