Improper Handling of Case Sensitivity

Overview tuf is a secure updater framework for Python. Affected versions of this package are vulnerable to Improper Handling of Case Sensitivity due to platform-dependent behavior in the DelegatedRole.istargetinpathpattern function. An attacker can bypass intended access restrictions by exploitin...

tuf has platform-dependent delegation path matching

DelegatedRole.istargetinpathpattern uses fnmatch.fnmatch to decide whether a given target path is authorized by a delegation's glob pattern. Python's fnmatch.fnmatch calls os.path.normcase on both arguments before matching. On POSIX hosts normcase is the identity function; on Windows hosts os.pat...

gnutls: GnuTLS: Policy bypass due to case-sensitive nameConstraints comparison

A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of nameConstraints labels, specifically for dNSName DNS or rfc822Name email constraints within excludedSubtrees or permittedSubtrees. A remote attacker can exploit this by crafting a leaf...

Important: gnutls

Issue Overview: GnuTLS didn't check that DTLS fragments claimed a consistent messagelength value. Additionally, a crucial array size check was missing, enabling an attacker to cause a heap overwrite. CVE-2026-33846 A flaw was found in gnutls. This vulnerability occurs because gnutls performs...

Apache Tomcat 11.0.0.M1 < 11.0.22 multiple vulnerabilities

The version of Tomcat installed on the remote host is prior to 11.0.22. It is, therefore, affected by multiple vulnerabilities as referenced in the fixedinapachetomcat11.0.22security-11 advisory. - DEPRECATED: Authentication Bypass Issues vulnerability in digest authentication in Apache Tomcat...

crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...

curl: cookie: case-insensitive path comparison in replace_existing() allows cookie eviction across distinct paths

Hi all, replaceexisting in lib/cookie.c compares cookie paths case-insensitively at two sites. On case-sensitive servers, /Admin and /admin are distinct resources and are supposed to produce distinct jar entries. Because libcurl conflates them, a Set-Cookie at one path silently evicts the cookie ...
