PalmOS 3.5.2 and earlier uses weak encryption to store the user password, which allows attackers with physical access to the Palm device to decrypt the password and gain access to the device.

Debugging utility in the backdoor mode of Palm OS 3.5.2 and earlier allows attackers with physical access to a Palm device to bypass access restrictions and obtain passwords, even if the system lockout mechanism is enabled.

Handspring Visor 1.0 and 1.0.1 with the VisorPhone Springboard module installed allows remote attackers to cause a denial of service (PalmOS crash and VisorPhone database corruption) by sending a large or crafted SMS image.

Palm OS 3.5h and possibly other versions, as used in Handspring Visor and Xircom products, allows remote attackers to cause a denial of service via a TCP connect scan, e.g. from nmap.

Apple Palm Desktop 4.0b76 and 4.0b77 creates world-readable backup files and folders when a hotsync is performed, which could allow a local user to obtain sensitive information.

PalmOS allows remote attackers to cause a denial of service (CPU consumption) via a flood of ICMP echo request (ping) packets.

Palm Desktop 4.1.4 and earlier stores user data with weak permissions under the application directory, which allows local users to obtain sensitive information (address books, calendar files, and todo lists of other users) via unspecified vectors. NOTE: The provenance of this information is unknown; the details are obtained solely from third party information.

The Find feature in Palm OS Treo smart phones operates despite the system password lock, which allows attackers with physical access to obtain sensitive information (memory contents) by doing (1) text searches or (2) paste operations after pressing certain keyboard shortcut keys.

Palm OS on Treo 650, 680, 700p, and 755p Smart phones allows remote attackers to cause a denial of service (device reset or hang) via a flood of large ICMP echo requests. NOTE: this is probably a different vulnerability than CVE-2003-0293.
