Multiple stack-based buffer overflows in the Research in Motion RIM AxLoader ActiveX control in AxLoader.ocx and AxLoader.dll in BlackBerry Application Web Loader 1.0 allow remote attackers to execute arbitrary code via unspecified use of the (1) load or (2) loadJad method.

The PDF distiller in the Attachment Service in Research in Motion (RIM) BlackBerry Enterprise Server (BES) 4.1.3 through 4.1.6, BlackBerry Professional Software 4.1.4, and BlackBerry Unite! before 1.0.3 bundle 28 performs delete operations on uninitialized pointers, which allows user-assisted remote attackers to execute arbitrary code via a crafted data stream in a .pdf file.

Multiple heap-based buffer overflows in the PDF distiller in the Attachment Service in Research in Motion (RIM) BlackBerry Enterprise Server (BES) 4.1.3 through 4.1.6, BlackBerry Professional Software 4.1.4, and BlackBerry Unite! before 1.0.3 bundle 28 allow user-assisted remote attackers to execute arbitrary code via (1) a crafted stream in a .pdf file, related to "symWidths"; or (2) a crafted data stream in a .pdf file, related to "bitmaps."

Format string vulnerability on the Research in Motion BlackBerry 7270 before 4.0 SP1 Bundle 108 allows remote attackers to cause a denial of service (blocked call reception and calling) via format string specifiers in an SIP INVITE message that lacks a host name in the Contact header.

The Research in Motion BlackBerry 7270 before 4.0 SP1 Bundle 108 does not properly manage transaction states, which allows remote attackers to cause a denial of service (temporary device hang) by sending a certain SIP INVITE message, but not providing an ACK when the call is answered.
