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): * 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 for git-lfs on Red Hat Enterprise Linux 9, addressing three vulnerabilities in Go components: CVE-2026-32282 allows Root.Chmod to follow symlinks outside the root directory, potentially leading to unauthorized file permission changes; CVE-2026-32283 is a denial of service vulnerability triggered by multiple TLS 1.3 key update messages; CVE-2026-32280 is a denial of service vulnerability in certificate chain building within crypto/x509. The advisory provides updated git-lfs packages (version 3.6.1-8.el9_7.1) for multiple architectures to mitigate these issues.
Potential Impact
Successful exploitation of CVE-2026-32282 could allow unauthorized modification of file permissions via symlink traversal. CVE-2026-32283 and CVE-2026-32280 could cause denial of service conditions in applications using the affected Go crypto/tls and crypto/x509 libraries, potentially disrupting TLS communications or certificate validation processes. These vulnerabilities impact systems running the affected git-lfs packages on Red Hat Enterprise Linux 9.
Mitigation Recommendations
Red Hat has released updated git-lfs packages (git-lfs-3.6.1-8.el9_7.1) for Red Hat Enterprise Linux 9 and related variants that address these vulnerabilities. Users should apply these updates promptly following Red Hat's update instructions at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated in the advisory.
