high Tenable Cloud Security Plugin ID 476132

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - An authenticated HTTPS origin can supply an HSTS `max-age` value that the parser accepts, but time
 serialization later fails to process. On 64-bit systems, extreme max-age values compute an absolute expiry
 within standard time integer limits that exceeds calendar time structure bounds. During cache saves, the
 original HSTS file is truncated before writing a temporary replacement; when serialization fails, the
 temporary file is deleted, leaving an empty or partial cache. Because the save error is silently ignored
 during cleanup, curl exits successfully despite the data loss. (CVE-2026-87863)

Solution

Update the curl library and its related packages to version 1:8.23.0-1+e1 or later.
