Debian DSA-086-1 : ssh-nonfree - remote root exploit

We have received reports that the 'SSH CRC-32 compensation attack detector vulnerability' is being actively exploited. This is the same integer type error previously corrected for OpenSSH in DSA-027-1. OpenSSH the Debian ssh package was fixed at that time, but ssh-nonfree and ssh-socks were not...

Debian DSA-273-1 : krb4 - Cryptographic weakness

A cryptographic weakness in version 4 of the Kerberos protocol allows an attacker to use a chosen-plaintext attack to impersonate any principal in a realm. Additional cryptographic weaknesses in the krb4 implementation permit the use of cut-and-paste attacks to fabricate krb4 tickets for...

Debian DSA-347-1 : teapop - SQL injection

teapop, a POP-3 server, includes modules for authenticating users against a PostgreSQL or MySQL database. These modules do not properly escape user-supplied strings before using them in SQL queries. This vulnerability could be exploited to execute arbitrary SQL code under the privileges of the...

Debian DSA-457-1 : wu-ftpd - several vulnerabilities

Two vulnerabilities were discovered in wu-ftpd : - CAN-2004-0148 Glenn Stewart discovered that users could bypass the directory access restrictions imposed by the restricted-gid option by changing the permissions on their home directory. On a subsequent login, when access to the user's home...

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-159-1 : python - insecure temporary files

Zack Weinberg discovered an insecure use of a temporary file in os.execvpe from os.py. It uses a predictable name which could lead execution of arbitrary code. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted from Debian...

Debian DSA-505-1 : cvs - heap overflow

Stefan Esser discovered a heap overflow in the CVS server, which serves the popular Concurrent Versions System. Malformed 'Entry' Lines in combination with Is-modified and Unchanged can be used to overflow malloced memory. This was proven to be exploitable. %NASLMINLEVEL 70300 C Tenable Network...

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...

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-050-1 : sendfile - broken privileges dropping, broken tempfile

Colin Phipps and Daniel Kobras discovered and fixed several serious bugs in the saft daemon sendfiled' which caused it to drop privileges incorrectly. Exploiting this a local user can easily make it execute arbitrary code under root privileges. %NASLMINLEVEL 70300 C Tenable Network Security, Inc...

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-213-1 : libpng - buffer overflow

Glenn Randers-Pehrson discovered a problem in connection with 16-bit samples from libpng, an interface for reading and writing PNG Portable Network Graphics format files. The starting offsets for the loops are calculated incorrectly which causes a buffer overrun beyond the beginning of the row...

Debian DSA-545-1 : cupsys - denial of service

Alvaro Martinez Echevarria discovered a problem in CUPS, the Common UNIX Printing System. An attacker can easily disable browsing in CUPS by sending a specially crafted UDP datagram to port 631 where cupsd is running. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and...

Debian DSA-426-1 : netpbm-free - insecure temporary files

netpbm is a graphics conversion toolkit made up of a large number of single-purpose programs. Many of these programs were found to create temporary files in an insecure manner, which could allow a local attacker to overwrite files with the privileges of the user invoking a vulnerable netpbm tool...

Debian DSA-387-1 : gopher - buffer overflows

gopherd, a gopher server from the University of Minnesota, contains a number of buffer overflows which could be exploited by a remote attacker to execute arbitrary code with the privileges of the gopherd process the 'gopher' user by default. %NASLMINLEVEL 70300 C Tenable Network Security, Inc.
