Vulnerability Assessment Details
Check for the version of the proftpd package
Detailed Explanation for this Vulnerability Assessment
The remote host is missing the patch for the advisory MDKSA-2006:217-1 (proftpd).
A stack-based buffer overflow in the sreplace function in ProFTPD 1.3.0
and earlier, permits remote attackers to cause a denial of service, as
demonstrated by vd_proftpd.pm, a 'ProFTPD remote exploit.'
Buffer overflow in the tls_x509_name_oneline function in the mod_tls
module, as used in ProFTPD 1.3.0a and earlier, and possibly other
products, permits remote attackers to execute arbitrary code via a large
data length argument, a different vulnerability than CVE-2006-5815.
ProFTPD 1.3.0a and earlier does not properly set the buffer size limit
when CommandBufferSize is specified in the configuration file, which
leads to an off-by-two buffer underflow. NOTE: in November 2006, the
role of CommandBufferSize was originally associated with CVE-2006-5815,
but this was an error stemming from an initial vague disclosure. NOTE:
ProFTPD developers dispute this issue, saying that the relevant memory
location is overwritten by assignment before further use within the
affected function, so this is not a vulnerability. (CVE-2006-6171)
Packages have been patched to correct these issues.
The previous update incorrectly linked the vd_proftd.pm issue with the
CommandBufferSize issue. These are two distinct issues and the previous
update only addressed CommandBufferSize (CVE-2006-6171), and the
mod_tls issue (CVE-2006-6170).
