Description

This security bulletin contains information about 5 vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2018-1544)

CWE-ID: CWE-120 - Buffer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear


The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to buffer overflow in db2exmig and db2exfm. A local attacker can trigger memory corruption and escalate privileges to the DB2 instance owner to execute arbitrary code with root privileges.


2) Buffer overflow (CVE-ID: CVE-2018-1565)

CWE-ID: CWE-120 - Buffer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear


The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to buffer overflow in db2exmig and db2exfm. A local attacker can trigger memory corruption and escalate privileges to the DB2 instance owner to execute arbitrary code with root privileges.


3) Buffer overflow (CVE-ID: CVE-2018-1488)

CWE-ID: CWE-120 - Buffer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear


The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to buffer overflow in db2licm. A local attacker can trigger memory corruption and escalate privileges to the DB2 instance owner to execute arbitrary code with root privileges.


4) Buffer overflow (CVE-ID: CVE-2018-1515)

CWE-ID: CWE-120 - Buffer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear


The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to buffer overflow in db2convert. A local attacker can trigger memory corruption and escalate privileges to the DB2 instance owner to execute arbitrary code with root privileges.


5) Stack-based buffer overflow (CVE-ID: CVE-2018-1459)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P/U:Clear


The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to stack based buffer overflow in Db2's rah.exe. A local attacker can trigger memory corruption and escalate privileges to the DB2 instance owner to execute arbitrary code with root privileges.
