Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Privilege escalation
EUVDB-ID: #VU15919
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-1780
CWE-ID:
CWE-61 - UNIX Symbolic Link (Symlink) Following
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The vulnerability exists due to improper privileges and access controls. A a local db2 instance owner can exploit a symbolic link attack to read/write/corrupt a file that he originally did not have permission to access and obtain root access to the system.
