Description
The Research in Motion BlackBerry 7270 with 4.0 SP1 Bundle 83 allows remote attackers to cause a denial of service (blocked call reception) via a malformed SIP invite message, possibly related to multiple format string specifiers in the From field, a spoofed source IP address, and limitations of the function stack frame.
