Google: net-misc/curl: security update to 18026.0.0

critical Tenable Self-Hosted Container Security Plugin ID 450446

Description

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

- This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to
pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting
done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected
to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due
to this bug, the local variable that means "let the host resolve the name" could get the wrong value
during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target
buffer instead of copying just the resolved address there. The target buffer being a heap based buffer,
and the host name coming from the URL that curl has been told to operate with. (CVE-2023-38545)

Solution

Update the net-misc/curl library and its related packages to version 18026.0.0 or later.
