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/.
Unspecified maintenance web pages in Avaya S87XX, S8500, and S8300 before CM 3.1.3, and Avaya SES allow remote authenticated users to execute arbitrary commands via shell metacharacters in unspecified vectors (aka "shell command injection").
