Description
This security bulletin contains information about 1 vulnerability.
1) Resource management error (CVE-ID: CVE-2016-7166)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.
libarchive before 3.2.0 does not limit the number of recursive decompressions, which allows remote attackers to cause a denial of service (memory consumption and application crash) via a crafted gzip file.
