https://notcve.org/view.php?id=CVE-2021-45960
01 Jan 2022 — In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory). En Expat (también se conoce como libexpat) versiones anteriores a 2.4.3, un desplazamiento a la izquierda por 29 (o más) lugares en la función storeAtts en el archivo xmlparse.c puede conllevar a un comportamiento incorrecto de reasignación (por ejemplo, asignar muy pocos bytes, o sólo liberar memoria). exp... • https://github.com/nanopathi/external_expat_AOSP10_r33_CVE-2021-45960 • CWE-130: Improper Handling of Length Parameter Inconsistency CWE-682: Incorrect Calculation •

CVE-2021-3711 – SM2 Decryption Buffer Overflow
https://notcve.org/view.php?id=CVE-2021-3711
24 Aug 2021 — In order to decrypt SM2 encrypted data an application is expected to call the API function EVP_PKEY_decrypt(). Typically an application will call this function twice. The first time, on entry, the "out" parameter can be NULL and, on exit, the "outlen" parameter is populated with the buffer size required to hold the decrypted plaintext. The application can then allocate a sufficiently sized buffer and call EVP_PKEY_decrypt() again, but this time passing a non-NULL value for the "out" parameter. A bug in the ... • http://www.openwall.com/lists/oss-security/2021/08/26/2 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

CVE-2021-3712 – Read buffer overruns processing ASN.1 strings
https://notcve.org/view.php?id=CVE-2021-3712
24 Aug 2021 — ASN.1 strings are represented internally within OpenSSL as an ASN1_STRING structure which contains a buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings which are repesented as a buffer for the string data which is terminated with a NUL (0) byte. Although not a strict requirement, ASN.1 strings that are parsed using OpenSSL's own "d2i" functions (and other similar parsing functions) as well as any string whose value has been set with the ASN1_STRING_set... • http://www.openwall.com/lists/oss-security/2021/08/26/2 • CWE-125: Out-of-bounds Read •
