Title
XZ Utils: Buffer overflow in lzma_index_append()
Summary
XZ Utils provide a general-purpose data-compression library plus command-line tools. Prior to version 5.8.3, if lzma_index_decoder() was used to decode an Index that contained no Records, the resulting lzma_index was left in a state where where a subsequent lzma_index_append() would allocate too little memory, and a buffer overflow would occur. This issue has been patched in version 5.8.3.

CVE-2024-3094 (GCVE-0-2024-3094)
Vulnerability from cvelistv5 – Published: 2024-03-29 16:51 – Updated: 2025-11-20 07:17

Title
Xz: malicious code in distributed source
Summary
Malicious code was discovered in the upstream tarballs of xz, starting with version 5.6.0.
Through a series of complex obfuscations, the liblzma build process extracts a prebuilt object file from a disguised test file existing in the source code, which is then used to modify specific functions in the liblzma code. This results in a modified liblzma library that can be used by any software linked against this library, intercepting and modifying the data interaction with this library.

CVE-2020-22916 (GCVE-0-2020-22916)
Vulnerability from cvelistv5 – Published: 2023-08-22 00:00 – Updated: 2024-10-29 13:27 Disputed
VLAI
Summary
An issue discovered in XZ 5.2.5 allows attackers to cause a denial of service via decompression of a crafted file. NOTE: the vendor disputes the claims of "endless output" and "denial of service" because decompression of the 17,486 bytes always results in 114,881,179 bytes, which is often a reasonable size increase.

CVE-2022-1271 (GCVE-0-2022-1271)
Vulnerability from cvelistv5 – Published: 2022-08-31 15:33 – Updated: 2025-06-09 14:56
VLAI
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.
