Detailsinfo

A vulnerability, which was classified as critical, has been found in Sun Solaris 8.0 (Operating System). Affected by this issue is an unknown function of the component xlock. The manipulation of the argument XFILESEARCHPATH/XUSERFILESEARCHPATH as part of a Environment Variable leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Heap overflow in xlock in Solaris 2.6 through 8 allows local users to gain root privileges via a long (1) XFILESEARCHPATH or (2) XUSERFILESEARCHPATH environmental variable.
