Directory traversal vulnerability in the OBEX FTP Service in the Microsoft Bluetooth stack in Windows Mobile 6 Professional, and probably Windows Mobile 5.0 for Pocket PC and 5.0 for Pocket PC Phone Edition, allows remote authenticated users to list arbitrary directories, and create or read arbitrary files, via a .. (dot dot) in a pathname. NOTE: this can be leveraged for code execution by writing to a Startup folder.

Microsoft ActiveSync 4.1, as used in Windows Mobile 5.0, uses weak encryption (XOR obfuscation with a fixed key) when sending the user's PIN/Password over the USB connection from the host to the device, which might make it easier for attackers to decode a PIN/Password obtained by (1) sniffing or (2) spoofing the docking process.

ageet AGEphone before 1.6.2, running on Windows Mobile 5 on the HTC HyTN Pocket PC device, allows remote attackers to (1) cause a denial of service (call disruption and device hang) via a SIP message with a malformed header and (2) cause a denial of service (call disruption, false ring indication, and device outage) via a SIP message with a malformed SDP delimiter.

Unspecified vulnerability in Microsoft Internet Explorer on Windows Mobile 5.0 allows remote attackers to cause a denial of service (loss of browser and other device functionality) via a malformed WML page, related to an "overflow state." NOTE: it is possible that this issue is related to CVE-2007-0685.

Pictures and Videos on Windows Mobile 5.0 and Windows Mobile 2003 and 2003SE for Smartphones and PocketPC allows user-assisted remote attackers to cause a denial of service (device hang) via a malformed JPEG file.

Internet Explorer on Windows Mobile 5.0 and Windows Mobile 2003 and 2003SE for Smartphones and PocketPC allows attackers to cause a denial of service (application crash and device instability) via unspecified vectors, possibly related to a buffer overflow.
