Avoid quadratic complexity in resolvePath in net/url
Previously, resolving relative paths containing parent directory ('..') segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead. Now, path resolution operates on a byte…

go-git: Malicious reference names may modify files outside the reference storage
go-git is an extensible git implementation library written in pure Go. Prior to 5.19.2 and 6.0.0-alpha.5, reference names are not sanitized before being used to construct on-disk paths under the reference storage directory, so a maliciously crafted reference …

oras-go: file store write outside workingDir via symlink traversal
oras-go is a Go library for managing OCI artifacts. Prior to 2.6.1, resolveWritePath() in content/file/file.go uses a lexical filepath.Rel check for workingDir and does not account for symlink traversal, so when AllowPathTraversalOnWrite=false an attacker-con…

Invoking Encrypted Client Hello privacy leak in crypto/tls
Handshakes which used Encrypted Client Hello could be de-anonymized by a passive network observer due to a disclosure of pre-shared key identities in the unencrypted client hello.

OpenTelemetry-Go's baggage parsing no longer caps raw header length
OpenTelemetry-Go is the Go implementation of OpenTelemetry. Versions 1.41.0 and 1.43.0 removed raw-length rejection and it causes `Parse` to process arbitrarily large/invalid baggage headers and log errors, enabling DoS via oversized inputs. Versions 1.42.0 a…

Malformed constraint may cause denial of service in golang.org/x/crypto/ssh/agent
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.

Unbounded memory consumption in golang.org/x/crypto/ssh
SSH servers parsing GSSAPI authentication requests do not validate the number of mechanisms specified in the request, allowing an attacker to cause unbounded memory consumption.

github.com/ulikunitz/xz leaks memory when decoding a corrupted multiple LZMA archives
xz is a pure golang package for reading and writing xz-compressed files. Prior to version 0.5.14, it is possible to put data in front of an LZMA-encoded byte stream without detecting the situation while reading the header. This can lead to increased memory co…

Helm Charts with Specific JSON Schema Values Can Cause Memory Exhaustion
Helm is a package manager for Charts for Kubernetes. Prior to version 3.18.5, it is possible to craft a JSON Schema file in a manner which could cause Helm to use all available memory and have an out of memory (OOM) termination. This issue has been resolved i…

containerd has an integer overflow in User ID handling
containerd is an open-source container runtime. A bug was found in containerd prior to versions 1.6.38, 1.7.27, and 2.0.4 where containers launched with a User set as a `UID:GID` larger than the maximum 32-bit signed integer can cause an overflow condition wh…

HTTP Proxy bypass using IPv6 Zone IDs in golang.org/x/net
Matching of hosts against proxy patterns can improperly treat an IPv6 zone ID as a hostname component. For example, when the NO_PROXY environment variable is set to "*.example.com", a request to "[::1%25.example.com]:80` will incorrectly match and not be prox…

Timing sidechannel for P-256 on ppc64le in crypto/internal/nistec
Due to the usage of a variable time instruction in the assembly implementation of an internal function, a small number of bits of secret scalars are leaked on the ppc64le architecture. Due to the way this function is used, we do not believe this leakage is en…

Non-linear parsing of case-insensitive content in golang.org/x/net/html
An attacker can craft an input to the Parse functions that would be processed non-linearly with respect to its length, resulting in extremely slow parsing. This could cause a denial of service.
