Red Hat Security Advisory: cups security update
Red Hat has issued a security advisory for the Common UNIX Printing System (CUPS) addressing two vulnerabilities: an authentication bypass in CUPS authorization handling (CVE-2025-58060) and a null pointer dereference in the ipp_read_io() function leading to a remote denial of service (CVE-2025-58364). These issues affect multiple Red Hat Enterprise Linux 9. 2 variants and related products. The advisory rates the update as important and provides updated packages to remediate these vulnerabilities. No known exploits are reported in the wild at this time. Users of affected Red Hat products should apply the provided updates to mitigate these security issues.
AI Analysis
Technical Summary
This advisory covers two security flaws in CUPS on Red Hat Enterprise Linux 9.2 and related distributions. CVE-2025-58060 is an authentication bypass vulnerability in CUPS authorization handling, categorized under CWE-287, which could allow unauthorized access. CVE-2025-58364 is a null pointer dereference in the ipp_read_io() function, categorized under CWE-476, which can cause a remote denial of service. Red Hat has released updated packages to fix these vulnerabilities. The advisory is classified as important by Red Hat Product Security, though no CVSS scores are provided. The vulnerabilities affect multiple architectures including x86_64, ppc64le, aarch64, and s390x.
Potential Impact
Successful exploitation of CVE-2025-58060 could allow an attacker to bypass authentication mechanisms in CUPS, potentially granting unauthorized access to printing services. CVE-2025-58364 could cause a remote denial of service by triggering a null pointer dereference in the ipp_read_io() function. Both vulnerabilities impact the availability and security of the CUPS printing system on affected Red Hat Enterprise Linux versions. No known exploits are currently reported in the wild.
Mitigation Recommendations
Red Hat has released updated CUPS packages for Red Hat Enterprise Linux 9.2 and related variants that address these vulnerabilities. Users should apply these official updates as detailed in the Red Hat advisory RHSA-2025:16591 and the referenced article https://access.redhat.com/articles/11258. Since this is an on-premises product, remediation requires manual update by system administrators. Patch status is confirmed by the vendor advisory. No additional mitigation steps are indicated by Red Hat.
