Cryptographic weakness found making real strength against coliisions:
collisions in the the full SHA-1 in 2**69 hash operations, much less than the brute-force attack of 2**80 operations based on the hash length.
Collisions in SHA-0 in 2**39 operations.
Collisions in 58-round SHA-1 in 2**33 operations.
DHTML ActiveX and Help allows code injection into context of different server. By combining this vulnerability it's psosible to execute code in local machine zone. This vulnerability can potentially be used for silent spyware/adware installation.
Privilege escalation during parsing files with COM structure (e.g. MS Office), buffer overflow on OLE objects, including MS Exchange MS-TNEF data format.
In specific configurations, for example if ran in chroot environment on IPv6 network, message relaying is not limited allowing relay to be used for SPAM sending.
By using LOAD command it's possible to load dynamic library with server process privileges. Buffer overflow on large cursor's arguments number. Protection bypass on functions execution.
