Gentoo: GLSA-200403-08 Moderate: oftpd Denial of Service

A remotely-exploitable overflow exists in oftpd, allowing an attacker to crash the oftpd daemon.. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 200403-08 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: oftpd DoS vulnerability Date: March 29, 2004 Bugs: #45738 ID: 200403-08 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= A remotely-exploitable overflow exists in oftpd, allowing an attacker to crash the oftpd daemon. Background ========= Quote from "oftpd is designed to be as secure as an anonymous FTP server can possibly be. It runs as non-root for most of the time, and uses the Unix chroot() command to hide most of the systems directories from external users - they cannot change into them even if the server is totally compromised! It contains its own directory change code, so that it can run efficiently as a threaded server, and its own directory listing code (most FTP servers execute the system "ls" command to list files)." Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- net-ftp/oftpd = 0.3.7 Description ========== Issuing a port command with a number higher than 255 causes the server to crash. The port command may be issued before any authentication takes place, meaning the attacker does not need to know a valid username and password in order to exploit this vulnerability. Impact ===== This exploit causes a denial of service. Workaround ========= While a workaround is not currently known for this issue, all users are advised to upgrade to thelatest version of the affected package. Resolution ========= All users should upgrade to the current version of the affected package: # emerge sync # emerge -pv "> =net-ftp/oftpd-0.3.7" # emerge "> =net-ftp/oftpd-0.3.7" References ========= [ 1 ] Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to This email address is being protected from spambots. You need JavaScript enabled to view it. or alternatively, you may file a bug at https://bugs.gentoo.org/. . A remote denial-of-service vulnerability exists in Gentoo's oftpd service. To mitigate potential threats, please upgrade immediately. For further information, consult GLSA 200403-08.. oftpd security,gentoo advisory,remote crash,denial of service,daemon security. .
