CVE-2002-2041: Buffer Overflow
Multiple buffer overflows in realtime operating system (RTOS) 6.1.0 allows local users to execute arbitrary code via (1) a long ABLANG environment variable in phlocale or (2) a long -u option to pkg-installer.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Prevent unprivileged local users from executing the vulnerable phlocale binary: restrict file permissions and/or enforce file ACLs so only trusted administrators can execute phlocale (for example, change ownership and set permissions such as chmod 750 /path/to/phlocale and chown root:admin /path/to/phlocale).
- Compensating control
Prevent unprivileged local users from executing the vulnerable pkg-installer binary: restrict file permissions and/or enforce file ACLs so only trusted administrators can run pkg-installer (for example, change ownership and set permissions such as chmod 750 /path/to/pkg-installer and chown root:admin /path/to/pkg-installer). Ensure untrusted accounts cannot invoke pkg-installer with the -u option by denying access to the binary.
- Operational
Inventory and identify all hosts running BlackBerry QNX Neutrino RTOS version 6.1.0 and locate installations containing the phlocale and pkg-installer binaries.
