CVE-2017-11757: Actian Pervasive Psql

Critical severity, CVSS 9.8. EPSS: 2.5% chance of exploitation in the next 30 days.

Heap-based buffer overflow in Actian Pervasive PSQL v12.10 and Zen v13 allows remote attackers to execute arbitrary code via crafted traffic to TCP port 1583. The overflow occurs after Server-Client encryption-key exchange. The issue results from an integer underflow that leads to a zero-byte allocation. The _srvLnaConnectMP1 function is affected.
