Description
This security bulletin contains information about 1 vulnerability.
1) Memory corruption (CVE-ID: CVE-2015-4491)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists due to integer overflow in the make_filter_table function in pixops/pixops.c in gdk-pixbuf. A remote attacker can submit specially crafted bitmap dimensions that are mishandled during scaling, trigger heap-based buffer overflow and cause the service to crash or execute arbitrary code with elevated privileges.
