Title: HP Tru64 UNIX Multiple Local and Remote Buffer Overflow Vulnerabilities

Severity: CRITICAL

Description:

HP has reported multiple local and remote buffer overflow vulnerabilities in various binaries that ship with Tru64 UNIX. HP has also announced an undisclosed denial of service issue in /usr/sbin/ping, which is covered in the advisory and addressed in the included fixes.

Many of the issues have been addressed in previous vendor advisories. HP has released a list of affected binaries, with the applicable vendor tracking numbers:

SSRT2277 /usr/bin/ypmatch
SSRT2261 /usr/sbin/traceroute
SSRT2260 /usr/sbin/lpc
/usr/bin/lprm
/usr/bin/lpq
/usr/bin/lpr
/usr/lbin/lpd
SSRT0796U /usr/bin/binmail
SSRT0794U /usr/bin/ipcs
SSRT2191 /usr/sbin/quot
SSRT2189 /usb/bin/at
SSRT2256 /usr/bin/ps
SSRT2275 /usr/bin/uux
/usr/bin/uucp
/usr/bin/csh
/usr/bin/rdist
/usr/bin/mh/inc
/usr/bin/mh/msgchk
/usr/sbin/imapd
/usr/bin/deliver
/sbin/.upd..loader
SSRT2193 /usr/dt/bin/mailcv
SSRT2280 /usr/dt/bin/dtterm
SSRT2282 /usr/dt/bin/dtsession
SSRT2274 /usr/dt/bin/rpc.ttdbserverd
SSRT2279 /usr/bin/X11/dxterm
SSRT2275 /usr/bin/X11/dxconsole
/usr/bin/X11/dxpause
/usr/bin/X11/dxsysinfo
SSRT2340 /usr/sbin/telnetd
SSRT2270 BIND resolver glibc
SSRT2309 rpc XDR_ARRAY

A number of these utilities may potentially be exploited by an attacker to execute code with elevated privileges or to cause a denial of service condition. The nature of these issues is that an attacker can corrupt memory with attacker-supplied values, which may potentially result in execution of arbitrary code.

In the instance of the local buffer overflows, exploitation of some of these binaries may not yield any extra privileges for the attacker, if they are not installed setuid/setgid. With remote buffer overflows, successful exploitation may allow an attacker to execute arbitrary code with the privileges of the user running the utility or server.

** This vulnerability record will be divided into multiple Bugtraq IDs when analysis of the individual issues is complete. Some of these issues may already be known. Where it is appropriate, existing Bugtraq IDs will also be updated to reflect the information in the advisory.
