Summary

xz security update

Details

XZ Utils is free general-purpose data compression software with a high compression ratio. XZ Utils were written for POSIX-like systems, but also work on some not-so-POSIX systems. XZ Utils are the successor to LZMA Utils. The core of the XZ Utils compression code is based on LZMA SDK, but it has been modified quite a lot to be suitable for XZ Utils. The primary compression algorithm is currently LZMA2, which is used inside the .xz container format. With typical files, XZ Utils create 30% smaller output than gzip and 15% smaller output than bzip2.

Security Fix(es):

The vulnerability exists due to insufficient validation when handling filenames with two or more newlines. A remote attacker can force zgrep or xzgrep to write arbitrary files on the system. The vulnerability allows a remote attacker to compromise an affected system.(CVE-2022-1271)

Severity

7.1 (High)

CVE-2022-1271 (GCVE-0-2022-1271)

Vulnerability from cvelistv5 – Published: 2022-08-31 15:33 – Updated: 2025-06-09 14:56

Summary

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.

Severity

8.8 (High)

When zgrep is applied on the attacker\u0027s chosen file name (for example, a crafted file name), this can overwrite an attacker\u0027s 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."

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
