Ubuntu Security Notice 6233-1 - It was discovered that YAJL was not properly performing bounds checks when decoding a string with escape sequences. If a user or automated system using YAJL were tricked into processing specially crafted input, an attacker could possibly use this issue to cause a denial of service. It was discovered that YAJL was not properly handling memory allocation when dealing with large inputs, which could lead to heap memory corruption. If a user or automated system using YAJL were tricked into running a specially crafted large input, an attacker could possibly use this issue to cause a denial of service.

A use-after-free vulnerability exists in the JavaScript engine of Foxit Software's PDF Reader, version 12.1.1.15289. A specially crafted PDF document can trigger the reuse of previously freed memory by manipulating form fields of a specific type. This can lead to memory corruption and arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.
