CVE-2016-2849

CVE-2016-2849 affects Botan: the library did not use a constant-time algorithm for modular inverse during ECDSA signing, enabling timing side-channel leakage that could reveal ECDSA secret keys. Affected are Botan versions before 1.10.13 and 1.11.x before 1.11.29. Impact is a remote attacker pote...

CVE-2015-5727

The BER decoder in Botan 1.10.x before 1.10.10 and 1.11.x before 1.11.19 allows remote attackers to cause a denial of service memory consumption via unspecified vectors, related to a length field...

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-2016-2196

Heap-based buffer overflow in the P-521 reduction function in Botan 1.11.x before 1.11.27 allows remote attackers to cause a denial of service memory overwrite and crash or execute arbitrary code via unspecified vectors...

CVE-2016-2850

Botan 1.11.x before 1.11.29 does not enforce TLS policy for 1 signature algorithms and 2 ECC curves, which allows remote attackers to conduct downgrade attacks via unspecified vectors...

CVE-2014-9742

CVE-2014-9742 : The Miller–Rabin primality test in Botan before 1.10.8 and in 1.11.x before 1.11.9 improperly uses a single random base, weakening cryptographic protection for Diffie–Hellman groups. Connected advisories confirm this vulnerability in Botan’s pre-1.10.8 and specific 1.11.x releases...

CVE-2014-9742

The Miller-Rabin primality check in Botan before 1.10.8 and 1.11.x before 1.11.9 improperly uses a single random base, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a DH group...

CVE-2015-7827

CVE-2015-7827 affects Botan cryptographic library: historical versions Bot an 1.10.x prior to 1.10.13 and 1.11.x prior to 1.11.22 are vulnerable. The root cause is a timing side-channel during PKCS#1 padding decoding, enabling remote attackers to mount million-message attacks. Public references i...

CVE-2015-7827

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 decoding of PKCS1 padding...

CVE-2015-5727

CVE-2015-5727 affects Botan BER decoder. Multiple connected advisories (Debian DSA-3565, OpenVAS NASL) confirm the issue: the BER decoder could allocate a large amount of memory when processing a length field, enabling a denial of service through memory exhaustion. Affected: Botan 1.10.x before 1...

CVE-2016-2196

CVE-2016-2196 affects Botan 1.11.x (before 1.11.27). A heap-based overflow in the P-521 reduction function allows remote attackers to cause a memory overwrite, DoS, or arbitrary code execution via unspecified vectors. Upgrade to Botan 1.11.27 or later to remediate; exploitation details are not sp...

CVE-2015-5726

The CVE-2015-5726 issue affects Botan BER decoder: an empty BIT STRING in ASN.1 data can cause a remote denial of service (application crash) in Botan 0.10.x before 1.10.10 and 1.11.x before 1.11.19. Debian advisories confirm fixes for botan1.10 in Jessie (upgrade to 1.10.8-2+deb8u1). If applicab...

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...
