PK00175: CORRUPTION OF LIBPATH ENVIRONMENT VARIABLE BY MOD_IBM_SSL PREVENTS SITEMINDER FROM STARTING EXTERNAL LLAWP PROCESS. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

![]() APAR status Closed as fixed if next. Error description Corruption of LIBPATH environment variable by mod_ibm_ssl prevents SiteMinder from starting external LLAWP process. Other modules for IHS could have similar problems starting external processes which need LIBPATH to resolve dependent libraries. A memory allocation defect in mod_ibm_ssl will be fixed so that LIBPATH is not corrupted. Notes: Analogous environment variables on other platforms, such as LD_LIBRARY_PATH, are also affected. This potentially affects IHS 2.x on all platforms. The occurrence of the problem symptom depends on other accidental aspects of the configuration. Many customers are not experiencing this issue, but with IHS configuration changes unrelated to mod_ibm_ssl or SiteMinder, the problem symptom can occur. Permanent fix: Any cumulative e-fix for IHS 2.0.x after PQ94389. Any future PTF for IHS 2.0.42.x after IHS 2.0.42.2. Any future PTF for IHS 2.0.47.x after IHS 2.0.47.1.Local fix Temporary fix: Customers should request a temporary fix for this problem from support. --------end of APAR description---------- Temporary fix for this customer using IHS 2.0.47.1 on AIX: mod_ibm_ssl_20471_fix.so # cksum mod_ibm_ssl_20471_fix.so 1872457640 182461 mod_ibm_ssl_20471_fix.so Activate this version of mod_ibm_ssl by editing the LoadModule directive for mod_ibm_ssl to reference the path to mod_ibm_ssl_20471_fix.so as the last parameter instead of "modules/mod_ibm_ssl.so". Important: If you upgrade to any later cumulative e-fix, prior to the point when this APAR fix is included, you need to obtain a matching temporary fix from IHS support.Problem summary mod_ibm_ssl used temporary buffer for the string LIBPATH=xxx (or LD_LIBRARY_PATH=xxx). After it was added to the environment variable table, the storage could be used for other purposes, such that the LIBPATH variable had an invalid value or was not found in the table at all.Problem conclusion Temporary fix Comments This APAR is being closed as Fixed If Next. There is a deficiency that we currently plan to fix if there is another release, fix pack, or cumulative e-fix.
