Avaya » Sip Enablement Services : Security Vulnerabilities, CVEs, (Denial of service)

The remote management interface in SIP Enablement Services (SES) Server in Avaya SIP Enablement Services 5.0, and Communication Manager (CM) 5.0 on the S8300C with SES enabled, proceeds with Core router updates even when a login is invalid, which allows remote attackers to cause a denial of service (messaging outage) or gain privileges via an update request.

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/.
