CVE-2025-58183

tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A maliciously-crafted archive containing a large number of sparse regions can cause a Reader to read an unbounded amount of data from the archive into memory. When reading from a compressed source, a small compressed input can result in large allocations.

When reading from a compressed source, a small compressed input could result in large allocations.(CVE-2025-58183)

In Go before 1.24.8 and 1.25.x before 1.25.2, when parsing DER payloads, memories were being allocated prior to fully validating the payloads. This permits an attacker to craft a big empty DER payload to cause memory exhaustion in functions such as asn1.Unmarshal, x509.ParseCertificateRequest, and ocsp.ParseResponse.(CVE-2025-58185)

In Go before 1.24.8 and 1.25.x before 1.25.2, The Reader.ReadResponse function constructed a response string through repeated string concatenation of lines. When the number of lines in a response is large, this could cause excessive CPU consumption.(CVE-2025-61724)

Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption (JWE), JSON Web Signature (JWS), and JSON Web Token (JWT) standards. Prior to 4.1.4 and 3.0.5, decrypting a JSON Web Encryption (JWE) object will panic if the alg field indicates a key wrapping algorithm (one ending in KW, with the exception of A128GCMKW, A192GCMKW, and A256GCMKW) and the encrypted_key field is empty. The panic happens when cipher.KeyUnwrap() in key_wrap.go attempts to allocate a slice with a zero or negative length based on the length of the encrypted_key. This code path is reachable from ParseEncrypted() / ParseEncryptedJSON() / ParseEncryptedCompact() followed by Decrypt() on the resulting object. Note that the parse functions take a list of accepted key algorithms. If the accepted key algorithms do not include any key wrapping algorithms, parsing will fail and the application will be unaffected. This panic is also reachable by calling cipher.KeyUnwrap() directly with any ciphertext parameter less than 16 bytes long, but calling this function directly is less common. Panics can lead to denial of service. This vulnerability is fixed in 4.1.4 and 3.0.5.(CVE-2026-34986)

A denial-of-service vulnerability exists in github.com/sirupsen/logrus when using Entry.Writer() to log a single-line payload larger than 64KB without newline characters. Due to limitations in the internal bufio.Scanner, the read fails with "token too long" and the writer pipe is closed, leaving Writer() unusable and causing application unavailability (DoS). This affects versions < 1.8.3, 1.9.0, and 1.9.2. The issue is fixed in 1.8.3, 1.9.1, and 1.9.3+, where the input is chunked and the writer continues to function even if an error is logged.(CVE-2025-65637)

Security Fix(es):

A vulnerability was found in Podman, Buildah, and CRI-O. A symlink traversal vulnerability in the containers/storage library can cause Podman, Buildah, and CRI-O to hang and result in a denial of service via OOM kill when running a malicious image using an automatically assigned user namespace (--userns=auto in Podman and Buildah). The containers/storage library will read /etc/passwd inside the container, but does not properly validate if that file is a symlink, which can be used to cause the library to read an arbitrary file on the host.(CVE-2024-9676)

Security Fix(es):

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)

If the PATH environment variable contains paths which are executables (rather than just directories), passing certain strings to LookPath ("", ".", and ".."), can result in the binaries listed in the PATH being unexpectedly returned.(CVE-2025-47906)

When using http.CrossOriginProtection, the AddInsecureBypassPattern method can unexpectedly bypass more requests than intended. CrossOriginProtection then skips validation, but forwards the original request path, which may be served by a different handler without the intended security protections.(CVE-2025-47910)

The Parse function permits values other than IPv6 addresses to be included in square brackets within the host component of a URL. RFC 3986 permits IPv6 addresses to be included within the host component, enclosed within square brackets. For example: "http://[::1]/". IPv4 addresses and hostnames must not appear within square brackets. Parse did not enforce this requirement.(CVE-2025-47912)

SSH Agent servers do not validate the size of messages when processing new identity requests, which may cause the program to panic if the message is malformed due to an out of bounds read.(CVE-2025-47914)

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. When cloning a repository Git knows to optionally fetch a bundle advertised by the remote server, which allows the server-side to offload parts of the clone to a CDN. The Git client does not perform sufficient validation of the advertised bundles, which allows the remote side to perform protocol injection. This protocol injection can cause the client to write the fetched bundle to a location controlled by the adversary. The fetched content is fully controlled by the server, which can in the worst case lead to arbitrary code execution. The use of bundle URIs is not enabled by default and can be controlled by the bundle.heuristic config option. Some cases of the vulnerability require that the adversary is in control of where a repository will be cloned to. This either requires social engineering or a recursive clone with submodules. These cases can thus be avoided by disabling recursive clones. This vulnerability is fixed in v2.43.7, v2.44.4, v2.45.4, v2.46.4, v2.47.3, v2.48.2, v2.49.1, and v2.50.1.(CVE-2025-48385)

QUIC connections do not set an upper bound on the amount of data buffered when reading post-handshake messages, allowing a malicious QUIC connection to cause unbounded memory growth. With fix, connections now consistently reject messages larger than 65KiB in size.(CVE-2023-39322)

Git LFS is a Git extension for versioning large files. In Git LFS versions 0.5.2 through 3.7.0, when populating a Git repository's working tree with the contents of Git LFS objects, certain Git LFS commands may write to files visible outside the current Git working tree if symbolic or hard links exist which collide with the paths of files tracked by Git LFS. The git lfs checkout and git lfs pull commands do not check for symbolic links before writing to files in the working tree, allowing an attacker to craft a repository containing symbolic or hard links that cause Git LFS to write to arbitrary file system locations accessible to the user running these commands. As well, when the git lfs checkout and git lfs pull commands are run in a bare repository, they could write to files visible outside the repository. The vulnerability is fixed in version 3.7.1. As a workaround, support for symlinks in Git may be disabled by setting the core.symlinks configuration option to false, after which further clones and fetches will not create symbolic links. However, any symbolic or hard links in existing repositories will still provide the opportunity for Git LFS to write to their targets.(CVE-2025-26625)

Gitk is a Tcl/Tk based Git history browser.

The script is run with the privileges of the user. 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.(CVE-2025-27614)
