cups: OpenPrinting CUPS: Remaining case-insensitive username matching in scheduler side paths (CVE-2026-27447 follow-up)

Two case-insensitive comparisons on request-derived usernames outside the main authorization path in CUPS's scheduler printer ACL validation and private-attribute filtering could allow bypass of username-based access controls in certain configurations...

Astra Linux – Vulnerability in cups

OpenPrinting CUPS is an open-source printing system for Linux and other Unix-like operating systems. In versions 2.4.12 and earlier, an unsafe deserialization attack and improper validation of printer attributes could lead to a null dereference in the libcups library. This is a remote DoS...

Astra Linux – Vulnerability in cups

OpenPrinting CUPS is an open-source printing system for Linux and other Unix-like operating systems. Prior to version 2.4.17, a network-attached attacker could send a crafted SNMP response to the CUPS SNMP backend, causing an out-of-bounds read of up to 176 bytes beyond the stack buffer. The leak...

Astra Linux – Vulnerability in cups

OpenPrinting CUPS is an open-source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and earlier, the RSS notifier allowed path traversal in notify-recipient-uri e.g., rss:///../job.cache, enabling a remote IPP client to write RSS XML bytes outside of CacheDir/r...

Astra Linux – Vulnerability in cups-filters

CUPS is a standards-based, open-source printing system. cups-browsed includes network printing functionality, which encompasses, but is not limited to, the ability to automatically discover print services and shared printers. cups-browsed binds to INADDRANY:631, allowing it to accept packets from...

Astra Linux – Vulnerability in cups-filters

CUPS is a standards-based, open-source printing system. libcupsfilters contains the code for the filters from the former cups-filters package, which serve as library functions for tasks related to data format conversion in Printer Applications.

Astra Linux – Vulnerability in Linux

A vulnerability was discovered in the Linux kernel. In the function printerioctl, there is an attempt to access a printerdev instance that has been deallocated. However, a use-after-free issue arises because the memory was previously freed by the gprinterfree function...

Astra Linux – Vulnerability in cups-filters

CUPS versions before 2.5b1 will send an HTTP POST request to an arbitrary destination and port in response to a single IPP UDP packet requesting the addition of a printer. This is a different vulnerability than CVE-2024-47176. The request is intended to test the new printer, but it can also be us...
