TITLE:
unrarlib "urarlib_get()" Multiple Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA24472

VERIFY ADVISORY:
http://secunia.com/advisories/24472/

CRITICAL:
Less critical

IMPACT:
Privilege escalation, System access

WHERE:
>From remote

SOFTWARE:
unrarlib 0.x
http://secunia.com/product/13654/

DESCRIPTION:
starcadi has reported some vulnerabilities in unrarlib, which
potentially can be exploited by malicious people to gain escalated
privileges or compromise a vulnerable system.

The vulnerabilities are caused due to boundary errors within the
"urarlib_get()" function in urarlib.c when processing the "filename",
"rarfile", and "libpassword" arguments. These can be exploited to
cause buffer overflows via setting an overly long string (greater
than 255 bytes) as one of the mentioned arguments.

Successful exploitation may allow execution of arbitrary code.

The vulnerabilities are reported in version 0.4.0. Other versions and
products that use the application may also be affected.

SOLUTION:
Do not process untrusted files in applications using the vulnerable
library.

PROVIDED AND/OR DISCOVERED BY:
starcadi
