A firmware downgrade prevention vulnerability has been identified in newer Lexmark devices.

A new feature to prevent Firmware downgrades was recently added to some Lexmark products. A method to override this downgrade protection has been identified.

A buffer overflow vulnerability has been identified in the Internet Printing Protocol (IPP) in various Lexmark devices.

A buffer overflow vulnerability has been identified in the Internet Printing Protocol (IPP) in various Lexmark devices. The vulnerability can be leveraged by an attacker to execute arbitrary code.

Race condition in the initialization process on Lexmark printers with firmware ATL before ATL.02.049, CB before CB.02.049, PP before PP.02.049, and YK before YK.02.049 allows remote attackers to bypass authentication by leveraging incorrect detection of the security-jumper status.

Lexmark printers with firmware ATL before ATL.021.063, CB before CB.021.063, PP before PP.021.063, and YK before YK.021.063 mishandle Erase Printer Memory and Erase Hard Disk actions, which allows physically proximate attackers to obtain sensitive information via direct read operations on non-volatile memory.
