Description

A local overflow exists in Sun Solaris. Solaris fails to handle an overly long LD_PRELOAD environment variable while launching SUID/SGID executables resulting in a stack based overflow. By setting LD_PRELOAD to a specially crafted value, an attacker can cause a deny of service or even execute arbitrary code with elevated priviledges resulting in a loss of integrity.

Attack Type: Input Manipulation
