cups: OpenPrinting CUPS: Authorization bypass via case-insensitive username comparison

A flaw was found in OpenPrinting CUPS. This authorization bypass vulnerability allows an unprivileged user to gain unauthorized access to restricted operations. This can be exploited by using a username that differs only in case from an authorized user during authorization checks...

cups: CUPS: Denial of Service and potential arbitrary code execution via use-after-free vulnerability when deleting temporary printers.

A flaw was found in CUPS, an open-source printing system. This vulnerability, known as a use-after-free, occurs in the CUPS scheduler when temporary printers are automatically removed. The system fails to properly manage memory, leaving a pointer to a freed memory location. An attacker could...

cups: Null Pointer Dereference in CUPS ipp_read_io() Leading to Remote DoS

A flaw was found in the CUPS printing system’s ippreadio function, which handles Internet Printing Protocol IPP requests. When processing specially crafted printer attribute responses, improper validation can cause a null pointer dereference. This leads to a crash in libcups, potentially disrupti...
