Description:
Some vulnerabilities have been reported in FreeRADIUS, which potentially can be exploited by malicious people to disclose certain sensitive information or cause a DoS (Denial of Service).
1) A boundary error in the handling of environment variables in the "radius_exec_program()" function in exec.c can potentially cause a stack-based buffer overflow and crash the system.
2) Off-by-one errors in token.c and sql_unixodbc.c can potentially cause a crash.
3) A boundary error in xlat.c when handling replies from the server may overflow a variable on the stack.
4) An error in validating the results of the "strftime()" function call in xlat.c can cause a memory leak of 40 bytes from the stack.
5) An error in escaping ldap data in rlm_ldap.c may disclose certain ldap data via a malformed query.
The vulnerabilities affect version 1.0.4. Prior versions may also be affected.
Solution:
Update to version 1.0.5.
