-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Trustix Secure Linux Security Advisory #2005-0018 Package name: gzip postgresql tcpdump vim Summary: Various security issues Date: 2005-05-06 Affected versions: Trustix Secure Linux 2.1 Trustix Secure Linux 2.2 Trustix Operating System - Enterprise Server 2 - -------------------------------------------------------------------------- Package description: gzip: The gzip package contains the popular GNU gzip data compression program. Gzipped files have a .gz extension. postgresql: PostgreSQL is an advanced Object-Relational database management system (DBMS) that supports almost all SQL constructs (including transactions, subselects and user-defined types and functions). The postgresql package includes the client programs and libraries that you'll need to access a PostgreSQL DBMS server. These PostgreSQL client programs are programs that directly manipulate the internal structure of PostgreSQL databases on a PostgreSQL server. These client programs can be located on the same machine with the PostgreSQL server, or may be on a remote machine which accesses a PostgreSQL server over a network connection. This package contains the docs in HTML for the whole package, as well as command-line utilities for managing PostgreSQL databases on a PostgreSQL server. tcpdump: Tcpdump is a command-line tool for monitoring network traffic. Tcpdump can capture and display the packet headers on a particular network interface or on all interfaces. Tcpdump can display all of the packet headers, or just the ones that match particular criteria. vim: VIM (VIsual editor iMproved) is an updated and improved version of the vi editor. Vi was the first real screen-based editor for UNIX, and is still very popular. VIM improves on vi by adding new features: multiple windows, multi-level undo, block highlighting and more. Problem description: gzip: - Ulf Härnhammar <> has discovered a vulnerability in gunzip that allows a malicious zip file to extract to an arbitrary directory of the attackers choice when gunzip is used with the -N option. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2005-1228 to this issue. - A race condition error in the file permission restore code, which may be exploited by a malicious local user, with write permissions, to gain read or write access to files of other users. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2005-0988 to this issue. postgresql: - Fix Character Conversion Vulnerability, gives public EXECUTE access to certain character conversion functions, which allows unprivileged users to call those functions with malicious values, with unknown impact. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2005-1409 to this issue. - Fix DOS Vulnerability, the (1) dex_init, (2) snb_en_init, (3) snb_ru_init, (4) spell_init, and (5) syn_init functions as "internal" even when they do not take an internal argument, which allows attackers to cause a denial of service (application crash). The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2005-1410 to this issue. tcpdump: - Fixed Multiple DoS issues: From The Common Vulnerabilities and Exposures project ( CAN-2005-1278: The isis_print function, as called by isoclns_print, in tcpdump 3.9.1 and earlier allows remote attackers to cause a denial of service (infinite loop) via a zero length, as demonstrated using a GRE packet. CAN-2005-1279: tcpdump 3.8.3 and earlier allows remote attackers to cause a denial of service (infinite loop) via a crafted (1) BGP packet, which is not properly handled by RT_ROUTING_INFO, or (2) LDP packet, which is not properly handled by the ldp_print function. CAN-2005-1280: The rsvp_print function in tcpdump 3.9.1 and earlier allows remote attackers to cause a denial of service (infinite loop) via a crafted RSVP packet of length 4. vim: - Fix tempfile creation bug,(CAN-2005-0069). The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2005-0069 to this issue. - Fix paths in vim.1 and vimtutor manpage (Bug #586) Action: We recommend that all systems with this package installed be upgraded. Please note that if you do not need the functionality provided by this package, you may want to remove it from your system.
