Debian DSA-444-1 : linux-kernel-2.4.17-ia64 - missing function return value check

Paul Starzetz and Wojciech Purczynski of isec.pl discovered a critical security vulnerability in the memory management code of Linux inside the mremap2 system call. Due to missing function return value check of internal functions a local attacker can gain root privileges. %NASLMINLEVEL 70300 C...

Debian DSA-119-1 : ssh -- local root exploit, remote client exploit

Joost Pol reports that OpenSSH versions 2.0 through 3.0.2 have an off-by-one bug in the channel allocation code. This vulnerability can be exploited by authenticated users to gain root privilege or by a malicious server exploiting a client with this bug. %NASLMINLEVEL 999999 @DEPRECATED@ This...

Debian DSA-478-1 : tcpdump - denial of service

tcpdump, a tool for network monitoring and data acquisition, was found to contain two vulnerabilities whereby tcpdump could be caused to crash through attempts to read from invalid memory locations. This bug is triggered by certain invalid ISAKMP packets. %NASLMINLEVEL 70300 C Tenable Network...

Debian DSA-300-1 : balsa - buffer overflow

Byrial Jensen discovered a couple of off-by-one buffer overflow in the IMAP code of Mutt, a text-oriented mail reader supporting IMAP, MIME, GPG, PGP and threading. This code is imported in the Balsa package. This problem could potentially allow a remote malicious IMAP server to cause a denial of...

Debian DSA-308-1 : gzip - insecure temporary files

Paul Szabo discovered that znew, a script included in the gzip package, creates its temporary files without taking precautions to avoid a symlink attack CAN-2003-0367. The gzexe script has a similar vulnerability which was patched in an earlier release but inadvertently reverted. %NASLMINLEVEL...

Debian DSA-371-1 : perl - XSS

A cross-site scripting vulnerability exists in the startform function in CGI.pm. This function outputs user-controlled data into the action attribute of a form element without sanitizing it, allowing a remote user to execute arbitrary web script within the context of the generated page. Any progr...

Debian DSA-430-1 : trr19 - missing privilege release

Steve Kemp discovered a problem in trr19, a type trainer application for GNU Emacs, which is written as a pair of setgid binaries and wrapper programs which execute commands for GNU Emacs. However, the binaries don't drop privileges before executing a command, allowing an attacker to gain access ...

Debian DSA-103-1 : glibc - buffer overflow

A buffer overflow has been found in the globbing code for glibc. This is the code which is used to glob patterns for filenames and is commonly used in applications like shells and FTP servers. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this...

Debian DSA-179-1 : gnome-gv - buffer overflow

Zen-parse discovered a buffer overflow in gv, a PostScript and PDF viewer for X11. The same code is present in gnome-gv. This problem is triggered by scanning the PostScript file and can be exploited by an attacker sending a malformed PostScript or PDF file. The attacker is able to cause arbitrar...

Debian DSA-127-1 : xpilot-server - remote buffer overflow

An internal audit by the xpilot a multi-player tactical manoeuvring game for X maintainers revealed a buffer overflow in xpilot server. This overflow can be abused by remote attackers to gain access to the server under which the xpilot server is running. %NASLMINLEVEL 70300 C Tenable Network...

Debian DSA-437-1 : cgiemail - open mail relay

A vulnerability was discovered in cgiemail, a CGI program used to email the contents of an HTML form, whereby it could be used to send email to arbitrary addresses. This type of vulnerability is commonly exploited to send unsolicited commercial email spam. %NASLMINLEVEL 70300 C Tenable Network...

Debian DSA-175-1 : syslog-ng - buffer overflow

Balazs Scheidler discovered a problem in the way syslog-ng handles macro expansion. When a macro is expanded a static length buffer is used accompanied by a counter. However, when constant characters are appended, the counter is not updated properly, leading to incorrect boundary checking. An...

Debian DSA-298-1 : epic4 - buffer overflows

Timo Sirainen discovered several problems in EPIC4, a popular client for Internet Relay Chat IRC. A malicious server could craft special reply strings, triggering the client to write beyond buffer boundaries. This could lead to a denial of service if the client only crashes, but may also lead to...

Debian DSA-206-1 : tcpdump - denial of service

The BGP decoding routines for tcpdump used incorrect bounds checking when copying data. This could be abused by introducing malicious traffic on a sniffed network for a denial of service attack against tcpdump, or possibly even remote code execution. %NASLMINLEVEL 70300 C Tenable Network Security...

Debian DSA-257-1 : sendmail - remote exploit

Mark Dowd of ISS X-Force found a bug in the header parsing routines of sendmail: it could overflow a buffer overflow when encountering addresses with very long comments. Since sendmail also parses headers when forwarding emails this vulnerability can hit mail-servers which do not deliver the emai...

Debian DSA-169-1 : htcheck - XSS

Ulf Harnhammar discovered a problem in ht://Check's PHP interface. The PHP interface displays information unchecked which was gathered from crawled external web servers. This could lead into a cross site scripting attack if somebody has control over the server responses of a remote web server whi...

Debian DSA-116-1 : cfs - buffer overflow

Zorgon found several buffer overflows in cfsd, a daemon that pushes encryption services into the Unixtm file system. We are not yet sure if these overflows can successfully be exploited to gain root access to the machine running the CFS daemon. However, since cfsd can easily be forced to die, a...
