security flaw

The line printer daemon (lpd) in the lpr package in multiple Linux operating systems authenticates by comparing the reverse-resolved hostname of the local machine to the hostname of the print server as returned by gethostname, which allows remote attackers to bypass intended access controls by modifying the DNS for the attacking IP.

dialog before 0.9a-20000118-3bis in Debian GNU/Linux allows local users to overwrite arbitrary files via a symlink attack.

security flaw

named in BIND 8.2 through 8.2.2-P6 allows remote attackers to cause a denial of service by sending an SRV record to the server, aka the "srv bug."

elvis-tiny before 1.4-10 in Debian GNU/Linux, and possibly other Linux operating systems, allows local users to overwrite files of other users via a symlink attack.

security flaw

rpc.statd in the nfs-utils package in various Linux distributions does not properly cleanse untrusted format strings, which allows remote attackers to gain root privileges.

security flaw

Some functions that implement the locale subsystem on Unix do not properly cleanse user-injected format strings, which allows local attackers to execute arbitrary commands via functions such as gettext and catopen.

security flaw

Kernel logging daemon (klogd) in Linux does not properly cleanse user-injected format strings, which allows local users to gain root privileges by triggering malformed kernel messages.

rpc.lockd in Red Hat Linux 6.1 and 6.2 allows remote attackers to cause a denial of service via a malformed request.

CUPS (Common Unix Printing System) 1.04 and earlier allows remote attackers to cause a denial of service via a malformed IPP request.

CUPS (Common Unix Printing System) 1.04 and earlier allows remote attackers to cause a denial of service via a CGI POST request.

CUPS (Common Unix Printing System) 1.04 and earlier does not properly delete request files, which allows a remote attacker to cause a denial of service.

CUPS (Common Unix Printing System) 1.04 and earlier allows remote attackers to cause a denial of service by authenticating with a user name that does not exist or does not have a shadow password.

Buffer overflow in Canna input system allows remote attackers to execute arbitrary commands via an SR_INIT command with a long user name or group name.

Buffer overflow in kon program in Kanji on Console (KON) package on Linux may allow local users to gain root privileges via a long -StartupMessage parameter.

Buffer overflow in fld program in Kanji on Console (KON) package on Linux may allow local users to gain root privileges via an input file containing long CHARSET_REGISTRY or CHARSET_ENCODING settings.

security flaw

gpm-root in the gpm package does not properly drop privileges, which allows local users to gain privileges by starting a utility from gpm-root.

IP masquerading in Linux 2.2.x allows remote attackers to route UDP packets through the internal interface by modifying the external source IP address and port number to match those of an established connection.

traceroute in NetBSD 1.3.3 and Linux systems allows local users to flood other systems by providing traceroute with a large waittime (-w) option, which is not parsed properly and sets the time delay for sending packets to zero.

traceroute in NetBSD 1.3.3 and Linux systems allows local unprivileged users to modify the source address of the packets, which could be used in spoofing attacks.

dump in Debian GNU/Linux 2.1 does not properly restore symlinks, which allows a local user to modify the ownership of arbitrary files.
