CVE-2020-22916 (GCVE-0-2020-22916)

Vulnerability from cvelistv5 – Published: 2023-08-22 00:00 – Updated: 2024-10-29 13:27

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.

Severity ?

5.5 (Medium)
