[GLSA-200409-18] cdrtools: Local root vulnerability in cdrecord if set SUID root Vulnerability Scan
Vulnerability Scan Summary
cdrtools: Local root vulnerability in cdrecord if set SUID root
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200409-18
(cdrtools: Local root vulnerability in cdrecord if set SUID root)
Max Vozeler discovered that the cdrecord utility, when set to SUID root,
fails to drop root rights before executing a user-supplied RSH program.
By default, Gentoo does not ship the cdrecord utility as SUID root and
therefore is not vulnerable. However, many users (and CD-burning
front-ends) set this manually after installation.
Impact
A local attacker could specify a malicious program using the $RSH
environment variable and have it executed by the SUID cdrecord, resulting
in root rights escalation.
Workaround
As a workaround, you could remove the SUID rights from your cdrecord
utility :
# chmod a-s /usr/bin/cdrecord

Solution:
All cdrtools users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=app-cdr/cdrtools-2.01_alpha37-r1"
# emerge ">=app-cdr/cdrtools-2.01_alpha37-r1"
Threat Level: High
