FreeBSD : nginx-devel -- multiple vulnerabilities (1ed77d8e-53bb-11f1-b339-3497f65b111b)

critical Nessus Plugin ID 315600

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 1ed77d8e-53bb-11f1-b339-3497f65b111b advisory.

 The nginx project reports:
 nginx 1.31.0 fixes multiple security issues affecting HTTP/2 proxying, rewrite handling, SCGI/uWSGI response handling, charset conversion, HTTP/3 connection migration, and OCSP resolver response processing.

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

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

Solution

Update the affected packages.
