HP Tru64 UNIX and TruCluster Server Version 5.1B-6 Patch Summary and Release Notes

• Eliminates compiler warnings in ln.
• Eliminates compiler warnings in ksh.
• Enhances the cron command to perform extensive logging.
• Fixes following problems in sh:
— A service denial problem that occurs when a quoted here doc script is executed.
— A problem with handling ELF files.
— A condition in which the shell variable $- does not hold the -C set option when it is
turned on.
— A condition that causes the printing of broken characters when the type built-in utility
of sh is invoked in the Japanese locale.
• Fixes a one-byte gap/hole in the maximum file size in the tar command before an extended
header record is used (8589934591 (octal 77777777777)).
• Fixes a problem in which nonsense characters are appended to the audit information output
of an execve event in brief mode.
• Installs DECthreads V3.20-033, which addresses the possibility of floating point errors in
threaded programs.
• Corrects a problem in which some networking applications, especially X.25 and X.29, stopped
working as expected because of interactions with security-related fixes and how the fstat()
function behaves on their sockets.
• Corrects a potential security vulnerability which may result in non-privileged users gaining
unauthorized access to files or privileged access on the system.
• Fixes an sh problem that occurs when executing command substitution.
• Fixes a fatal assertion error reported by pixie, hiprof, third spike, cord, uprofile and odump
object file tools for some executable files linked at optimization level 2 (-O2) or greater.
• Corrects a condition in which the system start-up script /sbin/rc2.d/S19security could cause
an unintended change in the system security configuration, which could occur when
/usr/bin/perl has been removed.
• Corrects a condition in which the mv command fails when operated on running binaries.
• Corrects a condition in which the mv command does not allow a file to be renamed even
though directory permissions allow it.
• Fixes a problem encountered with the Bourne shell when a file name with trailing slash (/)
is used as an argument to the command.
• Allows the mv command to parse the pathname correctly when a source directory ends in
trailing slash (/).
• Corrects the default UID displayed by the adduser command when UID_MAX exists in the
/etc/passwd file and helps prevent the duplication of UIDs.
• Corrects a potential security vulnerability in sendmail that could result in nonprivileged
users gaining unauthorized access to files or privileged access on the system. This potential
vulnerability may be in the form of a local or remote security domain risk.
• Corrects a condition that causes NIS clients to fail to connect to non-Tru64 NIS servers that
support only the V2 NIS protocol.
• Fixes a situation in which the header fields displayed by the output of the ps command are
not aligned properly.
• Corrects a problem with the class scheduler under the following conditions:
1. The class scheduler is started then stopped.
2. System owned semaphores are removed with the ipcrm -s command
3. The class scheduler fails to restart with the error "class_open: allocate or access
semaphore Invalid argument."
• Fixes a situation, in which the mkpasswd command dumps core when executed by a
nonprivileged user.
