Date: Fri, 8 Dec 2000 17:56:40 -0200 From: secure@CONECTIVA.COM.BR Subject: [CLA-2000:356] Conectiva Linux Security Announcement - joe To: BUGTRAQ@SECURITYFOCUS.COM -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ----------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - ----------------------------------------------------------------------- PACKAGE : joe SUMMARY : Symlink attack DATE : 2000-12-08 17:56:00 ID : CLA-2000:356 RELEVANT RELEASES : 4.0, 4.0es, 4.1, 4.2, 5.0, prg gráficos, ecommerce, 5.1, 6.0 - ---------------------------------------------------------------------- DESCRIPTION "joe" is a small text editor which is also shipped with Conectiva Linux. If joe is closed in a non-standard way (such as receiving an external TERM signal), it will create a file called DEADJOE in the directory where it was called from. If this file is a symbolic link, it will be followed. An attacker could create a symbolic link called DEADJOE in a directory and link it to sensitive system files. If the root user runs joe from that directory, and the program exits abnormally, it would add data to this sensitive file, probably corrupting it. SOLUTION All users of the joe editor should upgrade.
