[SECURITY] Fedora 24 Update: botan-1.10.13-1.fc24

Botan is a BSD-licensed crypto library written in C++. It provides a wide variety of basic cryptographic algorithms, X.509 certificates and CRLs, PKCS \10 certificate requests, a filter/pipe message processing system, and a wide variety of other features, all written in portable C++. The API...

Botan Heap Buffer Overflow Vulnerability

Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. Botan suffers from a heap buffer overflow vulnerability that allows remote attackers to conduct denial-of-service attacks...

Botan BER Decoder Security Bypass Vulnerability

Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A security vulnerability in the Botan BER decoder allows remote attackers to exploit the vulnerability by submitting a special request to read untrusted ASN.1 data...

Botan Denial of Service Vulnerability

Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. The Botan modular square root algorithm fails to properly condition check, allowing remote attackers to exploit this vulnerability for denial of service attacks...

Botan ECDSA Bypass Attack Vulnerability

Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A security vulnerability exists in Botan that allows remote attackers to exploit the vulnerability to perform a bypass attack on ECDSA...

Botan BER Decoder Denial of Service Vulnerability

Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. The Botan BER decoder fails to properly allocate memory for the 'length' field, allowing remote attackers to exploit the vulnerability by submitting a special request to invoke the OOM...

Botan RSA Decryption Vulnerability

Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A security vulnerability exists in Botan that allows remote attackers to perform RSA decryption by exploiting the vulnerability to perform a bypass attack...

botan -- multiple vulnerabilities

Jack Lloyd reports: Botan 1.10.13 has been released backporting some side channel protections for ECDSA signatures CVE-2016-2849 and PKCS 1 RSA decryption CVE-2015-7827...

FreeBSD : Multiple vulnerabilities in Botan (4cd9b19f-f66d-11e5-b94c-001999f8d30b)

The botan developers reports : Infinite loop in modular square root algorithm - The ressol function implements the Tonelli-Shanks algorithm for finding square roots could be sent into a nearly infinite loop due to a misplaced conditional check. This could occur if a composite modulus is provided,...

FreeBSD : Botan BER Decoder vulnerabilities (2004616d-f66c-11e5-b94c-001999f8d30b)

The botan developers reports : Excess memory allocation in BER decoder - The BER decoder would allocate a fairly arbitrary amount of memory in a length field, even if there was no chance the read request would succeed. This might cause the process to run out of memory or invoke the OOM killer...

botan: multiple issues

CVE-2016-2849 ECDSA side channel: ECDSA and DSA signature algorithms perform a modular inverse on the signature nonce k. The modular inverse algorithm used had input dependent loops, and it is possible a side channel attack could recover sufficient information about the nonce to eventually...

Updated botan packages fix security vulnerability

The BER decoder would crash due to reading from offset 0 of an empty vector if it encountered a BIT STRING which did not contain any data at all. This can be used to easily crash applicatons reading untrusted ASN.1 data, but does not seem exploitable for code execution CVE-2015-5726. The BER...

Fedora 22 : botan-1.10.12-1.fc22 / code-editor-2.8.1-13.fc22 / monotone-1.1-13.fc22 / etc (2016-1c08d77b96)

Security fix for CVE-2016-2194, CVE-2016-2195, CVE-2016-2196 Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional...
