CVE-2026-32884

Botan is a C++ cryptography library. Prior to version 3.11.0, during processing of an X.509 certificate path using name constraints which restrict the set of allowable DNS names, if no subject alternative name is defined in the end-entity certificate Botan would check that the CN was allowed by t...

CVE-2026-32884

CVE-2026-32884 — Botan (C++ crypto library) : Prior to version 3.11.0, during X.509 name constraints processing, Botan could mis-handle a mixed-case common name (CN) when no subject alternative name (SAN) is present. The CN check against DNS name constraints was effectively case-sensitive, allowi...

CVE-2026-32884 Botan: Case-Insensitive CN Values Bypass DNS excludedSubtrees Name Constraints (RFC 5280 Violation)

Botan is a C++ cryptography library. Prior to version 3.11.0, during processing of an X.509 certificate path using name constraints which restrict the set of allowable DNS names, if no subject alternative name is defined in the end-entity certificate Botan would check that the CN was allowed by t...

PT-2026-29125

Name of the Vulnerable Software and Affected Versions Botan versions 3.0.0 through 3.10.9 Description Botan is a C++ cryptography library. During X509 path validation, versions prior to 3.11.0 did not verify the signature of Online Certificate Status Protocol OCSP responses, only checking for an...

Botan 数据伪造问题漏洞

Botan is a C++ encryption library developed by Jack Lloyd as an individual project. Versions of Botan from 3.0.0 to 3.11.0 had a data manipulation vulnerability, which stemmed from the lack of signature verification for OCSP responses during the X509 path validation process...

PT-2026-29124

Name of the Vulnerable Software and Affected Versions Botan versions 2.3.0 through 3.10.9 Description Botan is a C++ cryptography library. During SM2 decryption, the code that checks the authentication code value C3 does not verify the encoded value's length before comparison. This can lead to a...

Astra Linux – Vulnerability in Botan

Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an object identifier or by explicitly encoding the parameters. A bug in the parsing of name constraint extensions in X.509 certificates meant that if the extension included both permitted and exclude...

Astra Linux – Vulnerability in Botan

Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an object identifier or by explicitly encoding the parameters. Before versions 3.5.0 and 2.19.5, checking name constraints in X.509 certificates was quadratic in terms of the number of names and name...

Updated botan2 packages fix security vulnerability

Botan before 3.6.0, when certain GCC versions are used, has a compiler-induced secret-dependent operation in lib/utils/donna128.h in donna128 used in Chacha-Poly1305 and x25519. An addition can be skipped if a carry is not set. This was observed for GCC 11.3.0 with -O2 on MIPS, and GCC on x86-i38...

ROS-20250911-10

A vulnerability in the lib/utils/ghash/ghash.cpp component of the Botan cryptographic library is related to the disclosure of information through an inconsistency. Exploitation of the vulnerability could allow an attacker acting remotely to gain access to sensitive data...

Linux Distros Unpatched Vulnerability : CVE-2017-14737

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A cryptographic cache-based side channel in the RSA implementation in Botan before 1.10.17, and 1.11.x and 2.x before 2.3.0, allows a local attacker to recover...

Linux Distros Unpatched Vulnerability : CVE-2015-7827

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Botan before 1.10.13 and 1.11.x before 1.11.22 make it easier for remote attackers to conduct million- message attacks by measuring time differences, related to...
