AI Analysis
Technical Summary
A stack-based buffer overflow vulnerability exists in Pgpool-II, allowing an unauthenticated attacker to cause abnormal process termination. The affected versions include 3.5.x through 4.7.2, specifically versions >=3.5.x <=4.2.x, >=4.3.0 <=4.3.20, >=4.4.0 <=4.4.17, >=4.5.0 <=4.5.12, >=4.6.0 <=4.6.7, and >=4.7.0 <=4.7.2. The vulnerability has a CVSS v3.0 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating network attack vector, low attack complexity, no privileges or user interaction required, no confidentiality or integrity impact, but high impact on availability.
Potential Impact
An unauthenticated attacker can exploit this vulnerability remotely to cause abnormal termination of the Pgpool-II process, resulting in denial of service. There is no reported impact on confidentiality or integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, consider limiting network exposure of Pgpool-II instances and monitoring for abnormal process terminations.
