NVDhttps://nvd.nist.gov/vuln/detail/CVE-2019-14818
CWEhttps://cwe.mitre.org/data/definitions/401.html

A flaw was found in all dpdk version 17.x.x before 17.11.8, 16.x.x before 16.11.10, 18.x.x before 18.11.4 and 19.x.x before 19.08.1 where a malicious master, or a container with access to vhost_user socket, can send specially crafted VRING_SET_NUM messages, resulting in a memory leak including file descriptors. This flaw could lead to a denial of service condition.

Weakness

The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.

Potential Mitigations

  • Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
  • For example, glibc in Linux provides protection against free of invalid pointers.
  • When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391].
  • To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
