- Summary
- CVE-2024-6874 affecting package cmake for versions less than 3.30.3-2
- Details
-
libcurl's URL API function curlurlget() 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.
