Security hole in syslogd-1.3.33

The syslogd server uses a Unix Domain stream socket (/dev/log) for receiving local log messages via syslog(3). Unix Domain stream sockets are non connection-less, that means, that one process is needed to serve one client.

Security hole in ypserv < 1.3.9

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

The package ypserv is the former "yellow pages", now called NIS information service, which is used for e.g. central network user account management. Several vulnerability exists: ypserv prior 1.3.9 allows an administrator in the NIS domain to inject password tables; rpc.yppasswd prior 1.3.6.92 has got a buffer overflow in the md5 hash generation [SuSE linux is unaffected by this, other linux falvors are]; rpc.yppasswdd prior 1.3.9 allows users to change GECO and login shell values of other users.

Security hole in cdwtools < 093

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

The cdwtools package is a frontend for various programs used to create CDs. Several buffer overflows and /tmp vulnerabilities exist in the cdwtools package. Thanks to Brock Tellier bringing this problem to our attention.

Security hole in ProFTPD

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Several buffer overflows have been found in proftpd which have been verified to be exploitable from an remote attacker. The fixing and finding of new holes is going on for over 2 weeks now, and there is no end in sight. Even with all known fixes, proftpd is still vulnerable to remote exploitation.

Security hole in lynx

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

When lynx calls external programs for protocols (e.g. telnet), the location is passed unchecked. This can be used to activate commandline parameters. For example, this reference [A HREF="telnet://-n.rhosts"]click me[/A] would activate the tracefile options on the telnet client, with the result, that a .rhosts in the current directory would created or overwritten.

Security hole in cron

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Three security threats were found in the vixie crond, which is shipped with SuSE Linux. 1) no boundchecking on a local buffer, while copying data from MAILTO 2) passing invalid options to sendmail 3) it doesn't drop root privileges while sending acknowledge mail to a user

Security hole in rsync

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

The security breach occurs when you try to transfer an empty directory into a non-existent directory. In that case rsync sets the permissions of the working directory to those of the empty directory; this means, that the permissions of your home directory are changed to the file access mode of the empty directory if you do a remote rsync by using ssh/rsh.

Security hole in netcfg

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

The way in.identd is started by inetd from a standard /etc/inetd.conf on a SuSE Linux distribution may be exploited to mount a Denial-of-Service attack against the system. When inetd starts in.identd with the "wait" flag and the "-w -t120" options, the in.identd will start to listen on the well known port while inetd deactivates its own listener for the time in.identd is alive.
