Problembeschreibung

A stack-based buffer overflow in the sreplace function in ProFTPD 1.3.0
and earlier, allows remote attackers to cause a denial of service, as
demonstrated by vd_proftpd.pm, a "ProFTPD remote exploit."
(CVE-2006-5815)

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, allows remote attackers to execute arbitrary code via a large
data length argument, a different vulnerability than CVE-2006-5815.
(CVE-2006-6170)

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.

Update:

The update for the Corporate 3.0 platforms had a bad patch for
CVE-2006-5815, which prevented some clients from being able to use the
server. This update corrects this issue.
