cdrecord in the cdrtools package before 2.01, when installed setuid root, does not properly drop privileges before executing a program specified in the RSH environment variable, which allows local users to gain privileges.
rscsi in cdrtools 2.01 and earlier allows local users to overwrite arbitrary files and gain root privileges by specifying the target file as a command line argument, which is modified while rscsi is running with privileges.
Format string vulnerability in scsiopen.c of the cdrecord program in cdrtools 2.0 allows local users to gain privileges via format string specifiers in the dev parameter.
