                Mandrake Linux Security Update Advisory

Package name:           cdrecord
Advisory ID:            MDKSA-2003:058
Date:                   May 15th, 2003

Affected versions:	8.2, 9.0, 9.1, Corporate Server 2.1

Problem Description:

 A vulnerability in cdrecord was discovered that can be used to obtain
 root access because Mandrake Linux ships with the cdrecord binary
 suid root and sgid cdwriter.
 Updated packages are provided that fix this vulnerability.  You may
 also elect to remove the suid and sgid bits from cdrecord manually,
 which can be done by executing, as root:
   chmod ug-s /usr/bin/cdrecord
 This is not required to protect yourself from this particular
 vulnerability, however.
