CVE-2024-7264
July 31, 2024
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.
