vpopmail multiple vulnerabilities

Description:

Inter7 vpopmail (vchkpw) versions 5.4.2 and earlier contain buffer overflows and format string vulnerabilities in the file vsybase.c

The buffer overflows are not fixed in versions 5.4.6/5.5.0, but are believed to be very hard to exploit, and only by administrators able to add users.
