1. Problem Description
Deprotect discovered a buffer overflow in execmail. After reviewing
our code we determined the whole MMDF package needed a security audit.
Various buffer overflows and other security issues that affect all
MMDF binaries have been corrected.
All but one of the MMDF binaries that were setuid root are no
longer setuid.
Additional changes in this version of MMDF are documented at
ftp://ftp.sco.com/pub/openserver5/507/mp/mp3/osr507mp3.html#rn507mp_mmdf
and in the updated man pages which are included in SCOSA-2004.7
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned MMDF buffer overflows the name CAN-2004-0510.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned MMDF null dereferences the name CAN-2004-0511.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned MMDF core dumps the name CAN-2004-0512.
