CVSS: 9.8EPSS: 4%CPEs: 7EXPL: 0CVE-2022-25236 – expat: Namespace-separator characters in "xmlns[:prefix]" attribute values can lead to arbitrary code execution
https://notcve.org/view.php?id=CVE-2022-25236
xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters into namespace URIs. El archivo xmlparse.c en Expat (también se conoce como libexpat) versiones anteriores a 2.4.5, permite a atacantes insertar caracteres separadores de espacios de nombres en URIs de espacios de nombres A flaw was found in expat. Passing one or more namespace separator characters in the "xmlns[:prefix]" attribute values made expat send malformed tag names to the XML processor on top of expat. This issue causes arbitrary code execution depending on how unexpected cases are handled inside the XML processor. • http://packetstormsecurity.com/files/167238/Zoom-XMPP-Stanza-Smuggling-Remote-Code-Execution.html http://www.openwall.com/lists/oss-security/2022/02/19/1 https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://github.com/libexpat/libexpat/pull/561 https://lists.debian.org/debian-lts-announce/2022/03/msg00007.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3UFRBA3UQVIQKXTBUQXDWQOVWNBKLERU https://lists.fedoraproject.org/archives/list/package- • CWE-179: Incorrect Behavior Order: Early Validation CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 7.5EPSS: 1%CPEs: 9EXPL: 0CVE-2022-23990 – expat: integer overflow in the doProlog function
https://notcve.org/view.php?id=CVE-2022-23990
Expat (aka libexpat) before 2.4.4 has an integer overflow in the doProlog function. Expat (también se conoce como libexpat) versiones anteriores a 2.4.4, presenta un desbordamiento de enteros en la función doProlog A flaw was found in expat. The vulnerability occurs due to large content in element type declarations when there is an element declaration handler present which leads to an integer overflow. This flaw allows an attacker to inject an unsigned integer, leading to a crash or a denial of service. • https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://github.com/libexpat/libexpat/pull/551 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/34NXVL2RZC2YZRV74ZQ3RNFB7WCEUP7D https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R7FF2UH7MPXKTADYSJUAHI2Y5UHBSHUH https://security.gentoo.org/glsa/202209-24 https://www.debian.org/security/2022/dsa-5073 https://www.oracle.com/security-alerts/cpuapr2022.html https://www. • CWE-190: Integer Overflow or Wraparound •
