CVE-2016-2195

Integer overflow in the PointGFp constructor in Botan before 1.10.11 and 1.11.x before 1.11.27 allows remote attackers to overwrite memory and possibly execute arbitrary code via a crafted ECC point, which triggers a heap-based buffer overflow. The bigintmul and bigintsqr functions received the...

CVE-2016-2850

CVE-2016-2850 affects Botan 1.11.x prior to 1.11.29. The vulnerability arises from Botan not enforcing TLS policy for (1) signature algorithms and (2) ECC curves, enabling remote attackers to perform downgrade attacks via unspecified vectors. The issue may allow attackers to bypass TLS policy and...

CVE-2016-2195

CVE-2016-2195 affects the Botan crypto library (C++). The root cause is an integer overflow in the PointGFp constructor used during ECC point decoding, which can trigger a heap-based buffer overflow when processing untrusted input. This could enable remote execution of code via a crafted ECC poin...

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,...

The vulnerability of Nettle’s cryptographic library allows attackers to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the ecc256modp function in the Nettle cryptographic library is related to errors in cryptographic transformations. Exploiting this vulnerability could allow a remote attacker to compromise the confidentiality, integrity, and accessibility of the protected information...
