CVE-2008-2812

Status Candidate

Overview

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 Security Notice 637-1
Posted Aug 27, 2008
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 637-1 - 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. The do_change_type routine did not correctly validation administrative users. A local attacker could exploit this to block mount points or cause private mounts to be shared, leading to denial of service or a possible loss of privacy. Tobias Klein discovered that the OSS interface through ALSA did not correctly validate the device number. A local attacker could exploit this to access sensitive kernel memory, leading to a denial of service or a loss of privacy. Zoltan Sogor discovered that new directory entries could be added to already deleted directories. A local attacker could exploit this, filling up available memory and disk space, leading to a denial of service.
