Red Hat Security Advisory: golang security update
The golang packages provide the Go programming language compiler. Security Fix(es): * cmd/go: cmd/go: Arbitrary file write via malicious pkg-config directive (CVE-2025-61731) * net/url: Incorrect parsing of IPv6 host literals in net/url (CVE-2026-25679) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
This advisory covers two security vulnerabilities in the golang packages provided by Red Hat Enterprise Linux 9.2. The first vulnerability (CVE-2025-61731) involves an arbitrary file write caused by a malicious pkg-config directive in the cmd/go tool. The second vulnerability (CVE-2026-25679) concerns incorrect parsing of IPv6 host literals in the net/url package. Both issues could potentially lead to security risks if exploited. Red Hat has released updated golang packages (version 1.19.13-24.el9_2) that address these vulnerabilities. The advisory applies to multiple architectures including x86_64, ppc64le, aarch64, and s390x. No CVSS scores are provided in the advisory, but the severity is rated as Important by Red Hat.
Potential Impact
The arbitrary file write vulnerability (CVE-2025-61731) could allow an attacker to write files arbitrarily via a crafted pkg-config directive, potentially leading to unauthorized file modifications. The incorrect parsing of IPv6 host literals (CVE-2026-25679) could cause improper handling of network addresses, which may affect applications relying on net/url for URL parsing. The overall impact is considered significant enough to warrant an Important severity rating by Red Hat. There are no known exploits in the wild at the time of this advisory.
Mitigation Recommendations
Red Hat has released updated golang packages (version 1.19.13-24.el9_2) that fix the described vulnerabilities. Users of affected Red Hat Enterprise Linux 9.2 systems should apply these updates promptly. Detailed instructions for applying the update are available at https://access.redhat.com/articles/11258. No additional mitigation actions are indicated by the vendor advisory.
