BIT-golang-2026-32281 — Inefficient policy validation in crypto/x509

Affected: Bitnami: golang

Validating certificate chains which use policies is unexpectedly inefficient when certificates in the chain contain a very large number of policy mappings, possibly causing denial of service. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots CertPool, or in the system certificate pool.

Withdrawn by the publisher.

Affected: CleanStart: gitness

Multiple security vulnerabilities affect the gitness package. During chain building, the amount of work that is done is not correctly limited when a large number of intermediate certificates are passed in VerifyOptions. See references for individual vulnerability details.

OESA-2026-3879 — git-lfs security update

Affected: openEuler:24.03-LTS-SP1: git-lfs

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):

The filepath.Walk and filepath.WalkDir functions are documented as not following symbolic links, but both functions are susceptible to a TOCTOU (time of check/time of use) race condition where a portion of the path being walked is replaced with a symbolic link while the walk is in progress.(CVE-2024-8244)

Gitk is a Tcl/Tk based Git history browser. Starting with 1.7.0, when a user clones an untrusted repository and runs gitk without additional command arguments, files for which the user has write permission can be created and truncated. The option Support per-file encoding must have been enabled before in Gitk's Preferences. This option is disabled by default. The same happens when Show origin of this line is used in the main window (regardless of whether Support per-file encoding is enabled or not). This vulnerability is fixed in 2.43.7, 2.44.4, 2.45.4, 2.46.4, 2.47.3, 2.48.2, 2.49.1, and 2.50.1.(CVE-2025-27613)

Proxy-Authorization and Proxy-Authenticate headers persisted on cross-origin redirects potentially leaking sensitive information.(CVE-2025-4673)
