OpenBase SQL as used in Apple Xcode gnutar binary code execution
| openbasesql-gnutar-code-execution (29624) |  High Risk |
Description:
OpenBase SQL as used in Apple Xcode could allow a local attacker to execute arbitrary code on the system caused by a vulnerability in an untrusted search path when the /Library/OpenBase/bin/gnutar binary is called while the OpenBase server is running. A local attacker could exploit this vulnerability using the TAR_OPTIONS environment variable to force a malformed gzip program to run without an absolute filename and manipulate a PATH variable to execute arbitrary code on the system with root privileges.
Platforms Affected:
- Apple, Xcode 2.2
- OpenBase International, OpenBase SQL 10.0 and prior
Remedy:
Upgrade to the latest J2SE 5.0-compliant OpenBase JDBC driver, available from the OpenBase Web site. See References.
For other distributions:
Contact your vendor for upgrade or patch information.
Consequences:
Gain Privileges
