IBM Security Proventia Network Active Bypass has addressed the following vulnerabilities. (CVE-2018-1000001, CVE-2017-16997, CVE-2017-1000408, CVE-2017-1000409, CVE-2017-17426)
CVEID: CVE-2017-17426 DESCRIPTION: GNU C Library (aka glibc or libc6) is vulnerable to a heap-based buffer overflow, caused by an integer overflow in the per-thread cache (aka tcache) feature. By allocating an object whose size is close to SIZE_MAX, a remote attacker could overflow a buffer and execute arbitrary code on the system.
