Description
This security bulletin contains information about 1 security vulnerability.
1) Integer overflow (CVE-ID: CVE-2016-9132)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
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.
Remediation
Install update from vendor's website.
