Alpine: libcurl, multiple curl packages: security update to 8.11.0-r0

medium Tenable Self-Hosted Container Security Plugin ID 423824

Description

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

 - When curl is asked to use HSTS, the expiry time for a subdomain might overwrite a parent domain's cache
 entry, making it end sooner or later than otherwise intended. This affects curl using applications that
 enable HSTS and use URLs with the insecure `HTTP://` scheme and perform transfers with hosts like
 `x.example.com` as well as `example.com` where the first host is a subdomain of the second host. (The HSTS
 cache either needs to have been populated manually or there needs to have been previous HTTPS accesses
 done as the cache needs to have entries for the domains involved to trigger this problem.) When
 `x.example.com` responds with `Strict-Transport-Security:` headers, this bug can make the subdomain's
 expiry timeout *bleed over* and get set for the parent domain `example.com` in curl's HSTS cache. The
 result of a triggered bug is that HTTP accesses to `example.com` get converted to HTTPS for a different
 period of time than what was asked for by the origin server. If `example.com` for example stops supporting
 HTTPS at its expiry time, curl might then fail to access `http://example.com` until the (wrongly set)
 timeout expires. This bug can also expire the parent's entry *earlier*, thus making curl inadvertently
 switch back to insecure HTTP earlier than otherwise intended. (CVE-2024-9681)
