Title: Solaris cachefsd Heap Overflow Vulnerability
Severity: CRITICAL
Description:
The Cache File System is a file system caching mechanism developed by Sun that improves NFS performance and scalability. It is shipped by default with the Solaris operating environment.
A remotely exploitable heap overflow condition has been reported in cachefsd. It is possible to cause the condition if the RPC procedure 'cachefsd_fs_mounted_1_svc()' is invoked with a cache name argument that is excessive in length.
When the cache name argument is processed, it is copied into another buffer using strcpy(). As strcpy() does not implement any bounds checking, a potential overrun condition exists. The overflow occurs in the heap and is reportedly exploitable as valid malloc() chunk structures are overwritten.
Successful attacks may result in remote attackers gaining root access on the affected system.
It has been reported that this vulnerability is being actively scanned for and exploited in the wild.
