Input validation error in IBM Db2

1) Input validation error

EUVDB-ID: #VU43781

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2012-2677

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Integer overflow in the ordered_malloc function in boost/pool/pool.hpp in Boost Pool before 3.9 makes it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a large memory chunk size value, which causes less memory to be allocated than expected.

Mitigation

Install update from vendor's website.
