CVE-2024-7264

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.

El código del analizador ASN1 de libcurl tiene la función `GTime2str()`, que se utiliza para analizar un campo de tiempo generalizado ASN.1. Si se proporciona un campo sintácticamente incorrecto, el analizador puede terminar usando -1 para la longitud de la *time fraction*, lo que lleva a que se ejecute una `strlen()` en un puntero a un área de búfer de almacenamiento dinámico que no está (intencionadamente) terminada en nulo. Este fallo probablemente lleve a un bloqueo, pero también puede llevar a que se devuelvan contenidos del montón a la aplicación cuando se utiliza [CURLINFO_CERTINFO](https://curl.se/libcurl/c/CURLINFO_CERTINFO.html).
