UBUNTU-CVE-2023-32324 (CVE-2023-32324)
Vulnerability from osv_ubuntu – Published: 2023-06-01 11:00 – Updated: 2026-04-22 07:45 – Source websiteOpenPrinting CUPS is an open source printing system. In versions 2.4.2 and prior, a heap buffer overflow vulnerability would allow a remote attacker to launch a denial of service (DoS) attack. A buffer overflow vulnerability in the function format_log_line could allow remote attackers to cause a DoS on the affected system. Exploitation of the vulnerability can be triggered when the configuration file cupsd.conf sets the value of loglevelto DEBUG. No known patches or workarounds exist at time of publication.
