Link to public exploit:

Vulnerability description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the __vsyslog_internal() function, which is called by both syslog() and vsyslog() while printing the SYSLOG_HEADER containing a long program name. A local user can pass a specially crafted input as arguments to the affected application, trigger a heap-based buffer overflow and execute arbitrary code on the system.
