This issue affects: All PAN-OS 7.1 and 8.0 versions; PAN-OS 8.1 versions earlier than 8.1.14; PAN-OS 9.0 versions earlier than 9.0.7. The resolved vulnerabilities include: CVE CVSS Summary os/unix/ngx_files.c in nginx before 1.10.1 and 7.5 (CVSS:3.0/ 1.11.x before 1.11.1 allows remote attackers to CVE-2016-4450 AV:N/AC:L/PR:N/ cause a denial of service (NULL pointer UI:N/S:U/C:N/ dereference and worker process crash) via a I:N/A:H) crafted request, involving writing a client request body to a temporary file. The default configuration of nginx, possibly 7.5 AV:N/AC:L/ 1.3.13 and earlier, uses world-readable CVE-2013-0337 Au:N/C:P/I:P/ permissions for the (1) access.log and (2) A:P error.log files, which allows local users to obtain sensitive information by reading the files. Product Status PAN-OS Versions Affected Unaffected 9.0 < 9.0.7 >= 9.0.7 8.1 < 8.1.14 >= 8.1.14 8.0 8.0.* 7.1 7.1.* Severity: HIGH CVSSv3.1 Base Score: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Solution These issues are fixed in PAN-OS 8.1.14, PAN-OS 9.0.7, and all later PAN-OS versions. PAN-OS 8.0 is now end-of-life as of October 31, 2019, and is no longer covered by our Product Security Assurance policies.
