Title:	Huawei EulerOS: Security Advisory for xz (EulerOS-SA-2022-1775)
Summary:	The remote host is missing an update for the Huawei EulerOS 'xz' package(s) announced via the EulerOS-SA-2022-1775 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'xz' package(s) announced via the EulerOS-SA-2022-1775 advisory. Vulnerability Insight: 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 Software/OS: 'xz' package(s) on Huawei EulerOS V2.0SP3. Solution: Please install the updated package(s). CVSS Score: 9.0 CVSS Vector: AV:N/AC:L/Au:S/C:C/I:C/A:C
