Patch Name: PHCO_27882 Patch Description: s700_800 10.24 (VVOS) libc cumulative patch Creation Date: 02/09/16 Post Date: 02/09/23 Hardware Platforms - OS Releases: s700: 10.24 s800: 10.24 Products: N/A Filesets: OS-Core.C-MIN OS-Core.CORE-SHLIBS ProgSupport.PROG-AUX ProgSupport.PROG-MIN Automatic Reboot?: Yes Status: General Release Critical: No Path Name: /hp-ux_patches/s700_800/10.X/PHCO_27882 Symptoms: PHCO_27882: Ported portions of HP-UX patch PHCO_26152 to VVOS Based upon portions of PHCO_26152: Problem with gethostby* library resolver while using dns for resolution. JAGae35468; SR 8606271239 gethostby* call may read past the end of the buffer while parsing the answer packet. JAGae37148; SR 8606273042 The library libc does not function properly. JAGae38579; SR 8606274502 PHCO_18432: snprintf() and vsnprintf() are not currently available in VVOS 10.24. PHCO_16602: strptime() treats Feb 29 2000 and March 1 2000 as the same day if the %A (or %a) and %U conversion specifications are used. JAGaa13581 JAGaa13581; SR 1653269738 PHCO_11693: The strptime and getdate calls do not handle two digit year specifications in the same manner. PHCO_11183: Call to tempnam(), mktemp() and mkstemp() sometimes returned a dangling symlink as the name for a temporary file. SR1653189134. Defect Description: PHCO_27882: Ported portions of HP-UX patch PHCO_26152 to VVOS Based upon portions of PHCO_26152: Under certain circumstances the resolver calls incorrectly calculates the available buffer size. Resolution: The buffer size is now calculated properly. JAGae35468; SR 8606271239 Under certain circumstances, the answer parsing function may try to read data past the end of buffer. Resolution: The buffer boundary checking condition is now corrected. JAGae37148; SR 8606273042 The library libc does not function properly. Resolution: Modified the libc code to correct the problem. JAGae38579; SR 8606274502 PHCO_18432: snprintf() and vsnprintf() are not currently available in VVOS 10.24. Due to the benefits to program reliability from using snprintf() and vsnprintf(), more programs will require their presence as time goes by. It is desirable, therefore, to make them available. PHCO_16602: strptime() returns the same values for the tm_mday, tm_mon, tm_yday and tm_wday fields in the tm structure for Feb 29 2000 and March 1 2000 if %A (or %a) and %U conversion specifications are used. The output for March 1 2000 is incorrect. PHCO_11693: The strptime and getdate calls do not handle two digit year specifications in the same manner. This has been addressed by providing strptime and getdate with an alternative behavior for dealing with two digit year specifications. In order to obtain the alternative behavior, which interprets two-digit year values in the range 66-99 to refer to the twentieth century and values in the range 00-68 to refer to the twenty-first century, the executable must link with the supplied object file, /usr/lib/year2000.o. Existing executables will continue to get the compatible behavior. PHCO_11183: The tempnam(), mktemp() and mkstemp() APIs did not check for a dangling symlink before returned it and this has been fixed now.
