XBlast is contains a locally exploitable buffer overflow vulnerability due to insufficient bounds checking of data supplied via the HOME environment variable. Successful exploitation would allow a local user to execute code with a gid of games.
|
|
|
|
/* 0x333xblast => xblast 2.6.1 local exploit
|
|
*
|
|
* xblast could be overflowed by passing a long $HOME
|
|
* env. For more info read advisory @ :
|
|
*

|
* http://www.0x333.org/advisories/outsider-003.txt
|
|
*
|
|
* * note * :
|
|
* exploit tested against xblast-2.6.beta-1.i386.rpm
|
|
* under Red Hat Linux 9.0. xblaste is not install
|
|
* by default +s.
