Patch 27070.00
OSFRCS540
• Corrects a potential security vulnerability where, under certain circumstances, system
integrity may be compromised. This may be in the form of improper file or privilege
management.
Patch 27071.00
OSFRIS540
• Corrects a joind failover problem and an extracted RIS area issue.
Patch 27072.00
OSFSCCS540
• Corrects a potential security vulnerability where, under certain circumstances, system
integrity may be compromised. This may be in the form of improper file or privilege
management.
• Provides protection against a class of potential security vulnerabilities called buffer overflows.
Buffer overflows are sometimes exploited in an attempt to subvert the function of a privileged
program and possibly execute commands at the elevated privileges if the program file has
the setuid privilege. This patch allows a system administrator to enable memory management
protections that limit potential buffer overflow vulnerabilities.
Patch 27073.00
OSFSDE540
• Fixes various problems in the dbx and object file tools: dbx, ostrip, strip, mcs, dis, cord, file,
and stdump.
• Fixes the way the spike code optimization tool handles -arch and -tune options. Using these
options with previous versions of spike resulted in unproductive error messages and/or
system crashes.
• Fixes a fatal assertion error reported by pixie, hiprof, third spike, cord, uprofile and odump
object file tools for some executables linked at optimization level 2 (-O2) or greater.
• Fixes an internal error with the /usr/bin/spike optimization command.
• Modifies the cflow utility to store its temporary files in a temporary directory created using
the /usr/bin/mktemp utility. If cflow cannot create a temporary directory it terminates with
an exit value of 1.
• Fixes a fatal error in /usr/bin/spike.
• Fixes a problem in which the prof -pixie -testcoverage <exe <exe.Counts sometimes reports
invalid source line number ranges.
• Changes the use of the configuration file /etc/svc.conf to /etc/nsswitch.conf to allow netgroup
data to be provided from LDAP, rather than only from NIS.
• Fixes performance tool failures on Sierra Clusters Parallel File Systems.
• Corrects an inaccurate error message in spike optimizer.
