Amazon Linux 2022 : golang, golang-bin, golang-misc (ALAS2022-2022-009)
medium Nessus Plugin ID 212473
Synopsis
The remote Amazon Linux 2022 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-009 advisory.A vulnerability was found in archive/zip of the Go standard library. Applications written in Go can panic or potentially exhaust system memory when parsing malformed ZIP files. (CVE-2021-33196)
There's an uncontrolled resource consumption flaw in golang's net/http library in the canonicalHeader() function. An attacker who submits specially crafted requests to applications linked with net/http's http2 functionality could cause excessive resource consumption that could lead to a denial of service or otherwise impact to system performance and resources. (CVE-2021-44716)
There's a flaw in golang's syscall.ForkExec() interface. An attacker who manages to first cause a file descriptor exhaustion for the process, then cause syscall.ForkExec() to be called repeatedly, could compromise data integrity and/or confidentiality in a somewhat uncontrolled way in programs linked with and using syscall.ForkExec(). (CVE-2021-44717)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Run 'dnf update --releasever=2022.0.20220125 golang' to update your system.See Also
