Description Patrick Del Bello 2024-07-31 04:36:11 UTC 
libcurl's ASN1 parser code has the `GTime2str()` function, used for parsing an ASN.1 Generalized Time field. If given an syntactically incorrect field, the parser might end up using -1 for the length of the *time fraction*, leading to a `strlen()` getting performed on a pointer to a heap buffer area that is not (purposely) null terminated.

This flaw most likely leads to a crash, but can also lead to heap contents getting returned to the application when
CURLINFO_CERTINFO (https://curl.se/libcurl/c/CURLINFO_CERTINFO.html) is used.

Comment 7 antal.nemes 2025-03-27 14:01:25 UTC 
For RedHat Enterprise Linux 8, RHSA-2025:1673 shows only mysql-related packages as updated, but CVE-2024-7264 is a vulnerability in libcurl, so I would expect libcurl and curl to be among the updated packages in this RHSA.

I checked the latest sources in RHEL8 and I do not see libcurl being updated with the upstream patch. Will there be an update for libcurl published for CVE-2024-7264 that includes this fix?
