In Botan 1.8.0 through 1.11.33, when decoding BER data an integer overflow could occur, which would cause an incorrect length field to be computed. Some API callers may use the returned (incorrect and attacker controlled) length field in a way which later causes memory corruption or other failure.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In Botan 1.8.0 through 1.11.33, when decoding BER data an integer overflow could occur, which would cause     an incorrect length field to be computed. Some API callers may use the returned (incorrect and attacker     controlled) length field in a way which later causes memory corruption or other failure. (CVE-2016-9132)

Note that Nessus relies on the presence of the package as reported by the vendor.

It was discovered that there was an integer overflow vulnerability in botan, a cryptography library. This could occur while parsing untrusted inputs such as X.509 certificates.

For Debian 7 'Wheezy', this problem has been fixed in version 1.10.5-1+deb7u2.

We recommend that you upgrade your botan1.10 packages.

### Botan 1.10.14 ###

  - NOTE WELL: Botan 1.10.x is supported for security     patches only until 2017-12-31

  - Fix integer overflow during BER decoding, found by Falko     Strenzke. This bug is not thought to be directly     exploitable but upgrading ASAP is advised.
    (CVE-2016-9132)

  - Fix two cases where (in error situations) an exception     would be thrown from a destructor, causing a call to     std::terminate.

  - When RC4 is disabled in the build, also prevent it from     being included in the OpenSSL provider. (GH #638)
