PublicDate: 2008-07-08
Candidate: CVE-2008-2812
References:
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2812
http://www.ubuntu.com/usn/usn-637-1
Description:
The Linux kernel before 2.6.25.10 does not properly perform tty operations,
which allows local users to cause a denial of service (system crash) or
possibly gain privileges via vectors involving NULL pointer dereference of
function pointers in (1) hamradio/6pack.c, (2) hamradio/mkiss.c, (3)
irda/irtty-sir.c, (4) ppp_async.c, (5) ppp_synctty.c, (6) slip.c, (7)
wan/x25_asy.c, and (8) wireless/strip.c in drivers/net/.
Ubuntu-Description:
It was discovered that there were multiple NULL-pointer function
dereferences in the Linux kernel terminal handling code. A local
attacker could exploit this to execute arbitrary code as root, or crash
the system, leading to a denial of service.
