A buffer overflow vulnerability has been identified in PostScript interpreter in various Lexmark devices. The vulnerability can be leveraged by an attacker to execute arbitrary code.
Se ha identificado una vulnerabilidad de desbordamiento del búfer en el intérprete PostScript de varios dispositivos Lexmark. Un atacante puede aprovechar la vulnerabilidad para ejecutar código arbitrario.
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Lexmark CX331adwe printers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the make42charstring method. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root.
