The X11 server that ships with Sun Microsystems' Solaris, Xsun, contains a locally exploitable buffer overflow vulnerability.
|
|
|
|
The condition is present when the value of the HOME environment variable is of excessive length (more than 1050 bytes long).
|
|
|
|
An attacker may exploit this vulnerability to execute arbitrary code with effective group 'root' privileges.
