medium Nessus Plugin ID 367753

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS / 26.10 host has packages installed that are affected by a vulnerability as referenced in the USN-8936-1 advisory.

 It was discovered that PHP did not properly validate the size of MySQL server packets in the mysqlnd driver. A malicious server could possibly use this issue to cause PHP to crash, resulting in a denial of service. This issue was only addressed in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, Ubuntu 26.04 LTS, and Ubuntu 26.10. (CVE-2025-1218)

 It was discovered that PHP incorrectly handled response buffer sizes in the SOAP HTTP client. A malicious server could possibly use this issue to cause PHP to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2025-14181)

 It was discovered that PHP incorrectly handled certain TAR archive headers in the Phar extension. An attacker could possibly use this issue to inject arbitrary files into a crafted archive. (CVE-2026-6103)

 It was discovered that PHP did not limit recursion depth when parsing certain SOAP requests. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service.
 (CVE-2026-91765)

 It was discovered that PHP incorrectly handled authentication headers when following HTTP redirects. A remote attacker could possibly use this issue to obtain sensitive information. (CVE-2026-91766)

 It was discovered that PHP incorrectly handled wildcard names in TLS server certificates. A malicious server could possibly use this issue to cause PHP to crash, resulting in a denial of service. This issue did not affect Ubuntu 14.04 LTS. (CVE-2026-91767)

 It was discovered that PHP incorrectly validated IPv6 client addresses in the FastCGI client access check.
 A remote attacker could possibly use this issue to bypass access restrictions. This issue did not affect Ubuntu 14.04 LTS. (CVE-2026-91768)

 It was discovered that PHP incorrectly performed TLS peer name verification. A remote attacker could possibly use this issue to impersonate a trusted server. (CVE-2026-91769)

 It was discovered that PHP incorrectly handled certain stream filter options. An attacker could possibly use this issue to obtain sensitive information. (CVE-2026-92842)

 It was discovered that PHP incorrectly handled empty Location headers when following HTTP redirects. A malicious server could possibly use this issue to redirect the client to an unintended location. This issue did not affect Ubuntu 14.04 LTS. (CVE-2026-93682)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution
