Red Hat Security Advisory: git-lfs security update
Git Large File Storage (LFS) replaces large files such as audio samples, videos, datasets, and graphics with text pointers inside Git, while storing the file contents on a remote server. Security Fix(es): * net/url: Incorrect parsing of IPv6 host literals in net/url (CVE-2026-25679) * golang: internal/syscall/unix: Root.Chmod can follow symlinks out of the root (CVE-2026-32282) * crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages (CVE-2026-32283) * crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building (CVE-2026-32280) 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 security fixes in git-lfs related to four CVEs: CVE-2026-25679 (incorrect parsing of IPv6 host literals in net/url), CVE-2026-32282 (Root.Chmod following symlinks outside root in golang internal syscall), CVE-2026-32283 (denial of service via multiple TLS 1.3 key update messages in golang crypto/tls), and CVE-2026-32280 (denial of service vulnerability in certificate chain building in golang crypto/x509). These vulnerabilities affect git-lfs as distributed in Red Hat Enterprise Linux 10 and its variants across multiple architectures. The advisory references updated git-lfs packages that address these issues.
Potential Impact
The vulnerabilities could allow denial of service conditions and potential security bypasses due to incorrect URL parsing and symlink handling. The denial of service issues affect TLS and certificate chain processing, potentially impacting the availability of services using git-lfs. The incorrect parsing of IPv6 literals and symlink traversal could lead to unexpected behavior or privilege escalation in certain contexts.
Mitigation Recommendations
Red Hat has released updated git-lfs packages for Red Hat Enterprise Linux 10 and its extended update support variants that address these vulnerabilities. Users should apply the git-lfs update as provided in Red Hat Advisory RHSA-2026:19133. Detailed update instructions are available at https://access.redhat.com/articles/11258. No additional mitigations are indicated beyond applying the official update.
