Vulnerability from variot
Buffer overflow vulnerability has been identified in Lexmark devices through 2021-12-07 in postscript interpreter. plural Lexmark A classic buffer overflow vulnerability exists on the device.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Crafted PostScript data can trigger a write past the end of an allocated buffer. This vulnerability allows local attackers to escalate privileges on affected installations of Lexmark MC3224i printers. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the remote object server. The issue results from the lack of an appropriate expiration mechanism for session IDs. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the web admin user. Lexmark is a line of printers in the United States

buffer overflow vulnerability exists on the device.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Crafted PostScript data can trigger a write past the end of an allocated buffer. This vulnerability allows local attackers to escalate privileges on affected installations of Lexmark MC3224i printers. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the remote object server. The issue results from the lack of an appropriate expiration mechanism for session IDs. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the web admin user.
