FKIE_CVE-2024-7264
Vulnerability from fkie_nvd - Published: 2024-07-31 08:15 - Updated: 2026-06-17 08:19
Severity
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
6.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
6.3 (Medium) - CVSS:3.1/
Summary
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.
