CVE-2020-4355
Status: ModifiedMedium (5.3)—
IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 9.7, 10.1, 10.5, 11.1, and 11.5 is vulnerable to a denial of service, caused by improper handling of Secure Sockets Layer (SSL) renegotiation requests. By sending specially-crafted requests, a remote attacker could exploit this vulnerability to increase the resource usage on the system. IBM X-Force ID: 178507.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
- Base score: 5.3
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 2.16%
- Percentile among all scored CVEs: 82
- Score date: 10/17/2026
