Canon Generic Plus Printer Drivers Out-of-Bounds Memory Access Vulnerability

A vulnerability allowing unallocated memory access has been identified in the print processing of various Canon Generic Plus Printer Drivers, including PCL6, UFR II, LIPS4, LIPSLX, and PS. This vulnerability arises when a malicious application sends a print job, potentially leading to memory crashes. Additionally, if this malicious print job coincides with one from a regular application, it could disrupt the normal printing process. However, this issue is unlikely to occur frequently, as it depends on the presence of an intentionally harmful program.

Impact

Exploitation of this vulnerability can cause out-of-bounds memory access, leading to memory corruption and potential Denial-of-Service conditions by disrupting the printing process.

Remediation

Users are advised to update to the latest version of the Canon Generic Plus Printer Drivers. The fixed versions for all affected driver types are 3.31 and higher.
