CVE-2017-6312: Debian Linux

Medium severity, CVSS 5.5. EPSS: 2% chance of exploitation in the next 30 days.

Integer overflow in io-ico.c in gdk-pixbuf allows context-dependent attackers to cause a denial of service (segmentation fault and application crash) via a crafted image entry offset in an ICO file, which triggers an out-of-bounds read, related to compiler optimizations.

Affected products

• Debian Debian Linux: version 8.0 only
• Fedoraproject Fedora: version 30 only; version 31 only
• Gnome Gdk-Pixbuf: before 2.36.12 (fixed in 2.36.12)
