Alpine: libcurl, multiple curl packages: security update to 8.12.0-r0

high Tenable Cloud Security Plugin ID 423827

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- When asked to use a `.netrc` file for credentials **and** to follow HTTP redirects, curl could leak the
password used for the first host to the followed-to host under certain circumstances. This flaw only
manifests itself if the netrc file has a `default` entry that omits both login and password. A rare
circumstance. (CVE-2025-0167)

- libcurl would wrongly close the same eventfd file descriptor twice when taking down a connection channel
after having completed a threaded name resolve. (CVE-2025-0665)

- When libcurl is asked to perform automatic gzip decompression of content-encoded HTTP responses with the
`CURLOPT_ACCEPT_ENCODING` option, **using zlib 1.2.0.3 or older**, an attacker-controlled integer overflow
would make libcurl perform a buffer overflow. (CVE-2025-0725)
