Multiple vulnerabilities including a buffer overflow and potential malicious code execution vulnerabilities have been fixed.. -------------------------------------------------------------------------- Debian Security Advisory DSA 316-3 This email address is being protected from spambots. You need JavaScript enabled to view it. Debian -- Security Information Matt Zimmerman June 17th, 2003 Debian -- Debian security FAQ -------------------------------------------------------------------------- Package : jnethack Vulnerability : buffer overflow, incorrect permissions Problem-Type : local Debian-specific: no CVE Id : CAN-2003-0358 CAN-2003-0359 The jnethack package is vulnerable to a buffer overflow exploited via a long '-s' command line option. This vulnerability could be used by an attacker to gain gid 'games' on a system where jnethack is installed. Additionally, some setgid binaries in the jnethack package have incorrect permissions, which could allow a user who gains gid 'games' to replace these binaries, potentially causing other users to execute malicious code when they run jnethack. For the stable distribution (woody) these problems have been fixed in version 1.1.5-11woody2. For the old stable distribution (potato) these problems have been fixed in version 1.1.3-4potato1. For the unstable distribution (sid) these problems are fixed in version 1.1.5-15. We recommend that you update your jnethack package.
