Publication date: 10 Jan 2021
Modification date: 10 Jan 2021
Type: security
Affected Mageia releases : 7
CVE: CVE-2020-28366 , CVE-2020-28367

Description

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.
An attacker could potentially use this flaw by creating a malicious repository
which would execute arbitrary code when downloaded and run via "go get" or 
"go build" whilst building a go project (CVE-2020-28367).
