FreeBSD is prone to a local denial-of-service vulnerability because it fails to handle exceptional conditions.
|
|
|
|
An attacker may leverage this issue to crash the affected computer, denying service to legitimate users. Under certain conditions, successful exploits may also corrupt the filesystem.
|
|
|
|
FreeBSD version 6.0-RELEASE-p5 and 6.1-RELEASE-p10 are vulnerable to this issue; other versions may also be affected.

Log: According to POSIX, the result of ftruncate(2) is unspecified
|
|
for file types other than VREG, VDIR and shared memory objects.
|
|
We already handle VREG, VLNK and VDIR cases. Silently ignore
|
|
truncate requests for all the rest. PR kern/98064

lol lol, thatz true. kokanin@gmail lolling it out in '06 !"#%&%(20061013)(="#"!
|
|
tested on FreeBSD 6.0-RELEASE-p5, 6.1-RELEASE-p10 (latest at the time of writing)
|
|
- it just makes the system reboot, and with a bit of luck fucks up the filesystem.
|
|
wow, that sort of makes this 0day local freebsd denial of service for non-CURRENT or whatever.
|
|
usage: ./run me and wait a moment.. woo, it's friday the 13th, go crash some shell providers.
