CVSS: 9.0EPSS: 1%CPEs: 12EXPL: 2CVE-2021-45960 – expat: Large number of prefixed XML attributes on a single tag can crash libexpat
https://notcve.org/view.php?id=CVE-2021-45960
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). expat (libexpat) is susceptible to a software flaw that causes process interruption. When processing a large number of prefixed XML attributes on a single tag can libexpat can terminate unexpectedly due to buffer overrun. The highest threat from this vulnerability is to availability. • http://www.openwall.com/lists/oss-security/2022/01/17/3 https://bugzilla.mozilla.org/show_bug.cgi?id=1217609 https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://github.com/libexpat/libexpat/issues/531 https://github.com/libexpat/libexpat/pull/534 https://security.gentoo.org/glsa/202209-24 https://security.netapp.com/advisory/ntap-20220121-0004 https://www.debian.org/security/2022/dsa-5073 https://www.tenable.com/security/tns-2022-05 https://acces • CWE-130: Improper Handling of Length Parameter Inconsistency CWE-682: Incorrect Calculation •

CVSS: 7.4EPSS: 0%CPEs: 56EXPL: 0CVE-2021-3712 – Read buffer overruns processing ASN.1 strings
https://notcve.org/view.php?id=CVE-2021-3712
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() function will additionally NUL terminate the byte array in the ASN1_STRING structure. However, it is possible for applications to directly construct valid ASN1_STRING structures which do not NUL terminate the byte array by directly setting the "data" and "length" fields in the ASN1_STRING array. This can also happen by using the ASN1_STRING_set0() function. • http://www.openwall.com/lists/oss-security/2021/08/26/2 https://cert-portal.siemens.com/productcert/pdf/ssa-244969.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=94d23fcff9b2a7a8368dfe52214d5c2569882c11 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=ccb0a11145ee72b042d10593a64eaf9e8a55ec12 https://kc.mcafee.com/corporate/index?page=content&id=SB10366 https://lists.apache.org/thread.html/r18995de860f0e63635f3008f • CWE-125: Out-of-bounds Read •
