With a specially crafted request, an attacker can cause a denial of service or execute arbitrary code with the privileges of the running daemon.\n## Solution Description\nCurrently, there are no known upgrades, patches, or workarounds available to correct this issue.\n## Short Description\nA remote overflow exists in MailCarrier. The server fails to properly check bounds on HELO and EHLO commands, resulting in a buffer overflow. With a specially crafted request, an attacker can cause a denial of service or execute arbitrary code with the privileges of the running daemon.\n## References:\nVendor URL: http://www.tabslab.com/en/product/mailcarrier20/\nSecurity Tracker: 1011939\n[Secunia Advisory ID:12999](https://secuniaresearch.flexerasoftware.com/advisories/12999/)\nPacket Storm: http://packetstormsecurity.org/0410-exploits/mailcarrier.txt\nMail List Post: http://archives.neohapsis.com/archives/bugtraq/2004-10/0274.html\nISS X-Force ID: 17861\n[CVE-2004-1638](https://vulners.com/cve/CVE-2004-1638)\n", "modified": "2004-10-26T11:35:50", "published": "2004-10-26T11:35:50", "href": "https://vulners.com/osvdb/OSVDB:11174", "id": "OSVDB:11174", "title": "MailCarrier HELO/EHLO Remote Overflow", "type": "osvdb", "cvss": {"score": 7.5, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:PARTIAL/I:PARTIAL/A:PARTIAL/"}}], "exploitdb": [{"lastseen": "2016-01-31T12:35:15", "bulletinFamily": "exploit", "description": "MailCarrier 2.51 Remote Buffer Overflow Exploit.
