HIGH Summary
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.

NASL family Debian Local Security Checks NASL id DEBIAN_DSA-3565.NASL description Several security vulnerabilities were found in botan1.10, a C++ library which provides support for many common cryptographic operations, including encryption, authentication, X.509v3 certificates and CRLs. - CVE-2015-5726 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 applications reading untrusted ASN.1 data, but does not seem exploitable for code execution. - CVE-2015-5727 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. - CVE-2015-7827 Use constant time PKCS #1 unpadding to avoid possible side channel attack against RSA decryption - CVE-2016-2194 Infinite loop in modular square root algorithm. The ressol function implementing 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, as this algorithm is only defined for primes. This function is exposed to attacker controlled input via the OS2ECP function during ECC point decompression. - CVE-2016-2195 Fix Heap overflow on invalid ECC point. - CVE-2016-2849 Use constant time modular inverse algorithm to avoid possible side channel attack against ECDSA. last seen 2020-06-01 modified 2020-06-02 plugin id 90841 published 2016-05-03 reporter This script is Copyright (C) 2016-2018 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/90841 title Debian DSA-3565-1 : botan1.10 - security update NASL family FreeBSD Local Security Checks NASL id FREEBSD_PKG_2004616DF66C11E5B94C001999F8D30B.NASL description 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.
