PatchTheCVECVE-2012-2677: Integer overflow in the ordered_malloc function in boost/pool/pool.hpp in Boost Pool before 3.9 makes it easie
CVE-2012-2677 is a medium-severity flaw (CVSS 5.0) affecting pool. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- EPSS top 10%: very likely to be exploited
- Public exploit reference
A fixed release or distro patch exists.
