Description of problem: Running subscription manager to register a host always end up with SIGSEGV on rhel 6.7. Executed command: /usr/bin/python -S /usr/sbin/subscription-manager register --org=CATS --activat Program terminated with signal 11, Segmentation fault. Version-Release number of selected component (if applicable): subscription-manager-1.14.10-1.el6.x86_64 libxml2-2.7.6-20.el6.x86_64 How reproducible: We could not reproduce this internally. But from the code: 2519 if ((xmlInputCallbackTable[i].opencallback == xmlGzfileOpen) && 2520 (strcmp(URI, "-") != 0)) { 2521 if (((z_stream *)context)->avail_in > 4) { 2522 char *cptr, buff4[4]; 2523 cptr = (char *) ((z_stream *)context)->next_in; 2524 if (gzread(context, buff4, 4) == 4) { 2525 if (strncmp(buff4, cptr, 4) == 0) 2526 ret->compressed = 0; 2527 else 2528 ret->compressed = 1; 2529 gzrewind(context); 2530 } 2531 } 2532 } The ((z_stream *)context)->avail_in seems not to be initialized since the xmlGzfileOpen callback just calls gzopen and there is no read operation done before it is being used. Also gzopen should return gzFile structure where I so not see a way it could be compatible with z_stream structure. Actual results: SIGSEGV - cptr = (char *) ((z_stream *)context)->next_in; points out of the allocated memory and it is also being used before any read operation. Expected results: The registration attempt will not fail on SIGSEGV
