CVE-2008-2812 – kernel: NULL ptr dereference in multiple network drivers due to missing checks in tty code

https://notcve.org/view.php?id=CVE-2008-2812

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/. El núcleo de Linux anterior a 2.6.25.10, no realiza de forma adecuada las operaciones tty, esto permite a usuarios locales provocar una denegación de servicio (caída del sistema) o posiblemente obtener privilegios mediante vectores que contienen referencias a puntero NULO en los punteros a funciones en (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, y (8) wireless/strip.c en drivers/net/. • http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.25.y.git%3Ba=commitdiff%3Bh=2a739dd53ad7ee010ae6e155438507f329dce788 http://kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.25.10 http://lists.opensuse.org/opensuse-security-announce/2008-07/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2008-07/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2008-07/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2008-10/msg00000.html http://l • CWE-476: NULL Pointer Dereference •
