Amazon Linux 2022 Security Advisory: ALAS-2022-058
Advisory Release Date: 2022-05-04 21:03 Pacific
Advisory Updated Date: 2022-05-06 16:19 Pacific
Severity:
Important
Issue Overview:
An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system. (CVE-2022-1271)
Affected Packages:
gzip, xz
Issue Correction:
Run dnf update --releasever=2022.0.20220504 gzip to update your system.
Run dnf update --releasever=2022.0.20220504xz to update your system.
