Description

CVE-2023-38545 affecting package cmake for versions less than 3.21.4-10

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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
