Multiple vulnerabilities have been identified in IBM DB2 for Linux, which could be exploited by local attackers to bypass security restrictions and obtain elevated privileges.
The first issue is due to errors in various setuid binaries that handle temporary files in an insecure manner, which could allow malicious users to conduct symlink attacks and create or overwrite arbitrary files with the privileges of the user invoking the vulnerable application.
The second vulnerability is due to errors in several set-uid binaries that manipulate local files insecurely, which could allow malicious users to write arbitrary data to any file on a vulnerable system by manipulating the "DB2INSTANCE" environment variable.
The third issue is due to buffer overflow errors when processing malformed environment variables, which could be exploited by local attackers gain "root" privileges.
