IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 9.7, 10.1, 10.5, and 11.1 is vulnerable to a buffer overflow, which could allow an authenticated local attacker to execute arbitrary code on the system as root. IBM X-Force ID: 155892.

IBM DB2 Accessories Suite for Linux, UNIX, and Windows, DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 9.7, 10.1, 10.5, 11.1, and 11.5 could allow a local authenticated attacker to execute arbitrary code on the system, caused by DLL search order hijacking vulnerability in Microsoft Windows client. By placing a specially crafted file in a compromised folder, an attacker could exploit this vulnerability to execute arbitrary code on the system. IBM X-Force ID: 188149.

IBM DB2 9.7, 10.1, 10.5, and 11.1 libdb2e.so.1 is vulnerable to a stack based buffer overflow, caused by improper bounds checking which could allow an attacker to execute arbitrary code. IBM X-Force ID: 153316.

IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 9.7, 10.1, 10.5, 11.1, and 11.5 could allow a local attacker to perform unauthorized actions on the system, caused by improper usage of shared memory. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information or cause a denial of service. IBM X-Force ID: 179989.

IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 9.7, 10.1, 10.5, 11.1, and 11.5 could allow an unauthenticated attacker to cause a denial of service due a hang in the SSL handshake response. IBM X-Force ID: 193660.

IBM DB2 for Linux, UNIX and Windows 9.7, 10,1, 10.5, and 11.1 (includes DB2 Connect Server) could allow a local user with DB2 instance owner privileges to obtain root access. IBM X-Force ID: 128058.

IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 9.7, 10.1, 10.5, 11.1, and 11.5 could allow a local user to obtain sensitive information using a race condition of a symbolic link. IBM X-Force ID: 179269.

IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 9.7, 10.1, 10.5, 11.1, and 11.5 could allow a local user to obtain sensitive information using a race condition of a symbolic link. IBM X-Force ID: 179268.

IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 10.1, 10.5, and 11.1 is vulnerable to a denial of service. Users that have both EXECUTE on PDGETDIAGHIST and access to the diagnostic directory on the DB2 server can cause the instance to crash. IBM X-Force ID: 158091.

IBM DB2 for Linux, UNIX and Windows 11.1 (includes DB2 Connect Server) under unusual circumstances, could expose highly sensitive information in the error log to a local user.
