CVE-2026-18568 XML::Sig versions from 0.29 before 0.72 for Perl allow signature verification bypass because verify returns true when every signature was skipped before any cryptographic check

XML::Sig versions from 0.29 before 0.72 for Perl allow signature verification bypass because verify returns true when every signature was skipped before any cryptographic check. verify in lib/XML/Sig.pm counts the //dsig:Signature elements into $numsigs and iterates over them, but two paths reach...

CVE-2026-9487

XML::Sig versions before 0.71 for Perl allow signature wrapping via duplicate ID. getsignedxml in lib/XML/Sig.pm, called from verify, resolves the SignedInfo Reference/@URI to a node with the XPath expression "//@ID='$id'" and returns the first node of the resulting node set. A document in which...

CVE-2026-35199 SymCrypt SymCryptXmssSign function - Heap overflow via 64->32-bit leaf-count truncation

SymCrypt is the core cryptographic function library currently used by Windows. From 103.5.0 to before 103.11.0, The SymCryptXmssSign function passes a 64-bit leaf count value to a helper function that accepts a 32-bit parameter. For XMSS^MT parameter sets with total tree height = 32 which include...

goxmldsig 安全漏洞

Goxmldsig is a digital signature library written in Go language by Russell Haering. This library inherits from SAML 2.0, allowing signature generation and verification functions to be performed without the need for command-line tools. Versions of goxmldsig prior to 1.6.0 contained security...

Debian DSA-4588-1 : python-ecdsa - security update

It was discovered that python-ecdsa, a cryptographic signature library for Python, incorrectly handled certain signatures. A remote attacker could use this issue to cause python-ecdsa to either not warn about incorrect signatures, or generate exceptions resulting in a denial-of-service. C Tenable...

USN-4196-1: python-ecdsa vulnerabilities

It was discovered that python-ecdsa incorrectly handled certain signatures. A remote attacker could possibly use this issue to cause python-ecdsa to generate unexpected exceptions, resulting in a denial of service. CVE-2019-14853 It was discovered that python-ecdsa incorrectly verified DER encodi...
