MGASA-2021-0018 - Updated golang packages fix security vulnerabilities

Publication date: 10 Jan 2021
URL: https://advisories.mageia.org/MGASA-2021-0018.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2020-28366,
     CVE-2020-28367

An input validation vulnerability was found in go. From a generated go file
(from the cgo tool) it is possible to modify symbols within that object file
and specify code instead. An attacker could potentially use this flaw by
creating a repository which included malicious pre-built object files that
could execute arbitrary code when downloaded and run via "go get" or "go build"
whilst building a go project (CVE-2020-28366).

An input validation vulnerability was found in go. If cgo is specified in a go
file, it is possible to bypass the validation of arguments to the gcc compiler.
