Description

CVE-2024-6874 affecting package curl for versions less than 8.8.0-1

libcurl's URL API function

[curl_url_get()](https://curl.se/libcurl/c/curl_url_get.html) offers punycode

conversions, to and from IDN. Asking to convert a name that is exactly 256

bytes, libcurl ends up reading outside of a stack based buffer when built to

use the *macidn* IDN backend. The conversion function then fills up the

provided buffer exactly - but does not null terminate the string.

This flaw can lead to stack contents accidently getting returned as part of

the converted string.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity none, availability none.
