Debian LTS Advisory DLA-3479-1 [email protected]

Package : golang-yaml.v2
Version : 2.2.2-1+deb10u1
CVE ID : CVE-2021-4235 CVE-2022-3064

Two denial of service vulnerabilities have been discovered in
golang-yaml.v2, a library which provides YAML support for the Go
language.

CVE-2021-4235

Due to unbounded alias chasing, a maliciously crafted YAML file can
cause the system to consume significant system resources. If parsing
user input, this may be used as a denial of service vector.

CVE-2022-3064

Parsing malicious or large YAML documents can consume excessive
amounts of CPU or memory.

Thanks to Scarlett Moore for working on preparing this update.

For Debian 10 buster, these problems have been fixed in version
2.2.2-1+deb10u1.

We recommend that you upgrade your golang-yaml.v2 packages.

For the detailed security status of golang-yaml.v2 please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/golang-yaml.v2
