{"id":"CVE-2006-6171","details":"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 a vague initial 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","modified":"2026-04-10T03:38:37.196288Z","published":"2006-11-30T15:28:00Z","database_specific":{"isDisputed":true},"references":[{"type":"ADVISORY","url":"http://proftp.cvs.sourceforge.net/proftp/proftpd/src/main.c?r1=1.292&r2=1.293&sortby=date"},{"type":"ADVISORY","url":"http://secunia.com/advisories/23174"},{"type":"ADVISORY","url":"http://secunia.com/advisories/23179"},{"type":"ADVISORY","url":"http://secunia.com/advisories/23184"},{"type":"ADVISORY","url":"http://secunia.com/advisories/23207"},{"type":"ADVISORY","url":"http://secunia.com/advisories/23329"},{"type":"ADVISORY","url":"http://www.debian.org/security/2006/dsa-1218"},{"type":"ADVISORY","url":"http://www.debian.org/security/2006/dsa-1222"},{"type":"ADVISORY","url":"http://www.mandriva.com/security/advisories?name=MDKSA-2006:217-1"},{"type":"ADVISORY","url":"http://www.openpkg.com/security/advisories/OpenPKG-SA-2006.035.html"},{"type":"ADVISORY","url":"https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=214820"},{"type":"WEB","url":"http://slackware.com/security/viewer.php?l=slackware-security&y=2006&m=slackware-security.502491"},{"type":"WEB","url":"http://www.gentoo.org/security/en/glsa/glsa-200611-26.xml"},{"type":"WEB","url":"http://www.trustix.org/errata/2006/0070"}],"schema_version":"1.7.5"}
