Updated botan packages fix security vulnerabilitiesPublication date: 01 Sep 2017

CVE: CVE-2016-9132 , CVE-2017-2801
While decoding BER length fields, an integer overflow could occur. This could occur while parsing untrusted inputs such as X.509 certificates. The overflow does not seem to lead to any obviously exploitable condition, but exploitation cannot be positively ruled out. Only 32-bit platforms are likely affected; to cause an overflow on 64-bit the parsed data would have to be many gigabytes (CVE-2016-9132). Aleksandar Nikolic discovered that an error in the x509 parser of the Botan crypto library could result in an out-of-bounds memory read, resulting in denial of service or an information leak if processing a malformed certificate (CVE-2017-2801).
