Alpine: multiple libuv packages: security update to 1.48.0-r0

high Tenable Cloud Security Plugin ID 424079

Description

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

 - libuv is a multi-platform support library with a focus on asynchronous I/O. The `uv_getaddrinfo` function
 in `src/unix/getaddrinfo.c` (and its windows counterpart `src/win/getaddrinfo.c`), truncates hostnames to
 256 characters before calling `getaddrinfo`. This behavior can be exploited to create addresses like
 `0x00007f000001`, which are considered valid by `getaddrinfo` and could allow an attacker to craft
 payloads that resolve to unintended IP addresses, bypassing developer checks. The vulnerability arises due
 to how the `hostname_ascii` variable (with a length of 256 bytes) is handled in `uv_getaddrinfo` and
 subsequently in `uv__idna_toascii`. When the hostname exceeds 256 characters, it gets truncated without a
 terminating null byte. As a result attackers may be able to access internal APIs or for websites (similar
 to MySpace) that allows users to have `username.example.com` pages. Internal services that crawl or cache
 these user pages can be exposed to SSRF attacks if a malicious user chooses a long vulnerable username.
 This issue has been addressed in release version 1.48.0. Users are advised to upgrade. There are no known
 workarounds for this vulnerability. (CVE-2024-24806)
