Fix for ticket #361 (searching RPM package after build).

File size: 103.1 KB
Line 
13.1.4:
2 * search RPM in $HOME/rpmbuild if test -d _topdir fails (CentOS
3 recommends '%(echo $HOME)/topdir', reported by E. Taft)
4
53.1.3:
6 * remove initgroups() from the popen call in unix entropy gatherer
7 * Add error message for update mode if local baseline cannot be found
8
93.1.2:
10 * Fixed incorrect memset in sh_checksum.c (sha256)
11 * Circumvent a gcc compiler bug with inline asm (gcc 4.8)
12 * Allow multiple exclusions for SUID check
13 * Use calloc instead of malloc
14 * Add overflow check in minilzo.c (but the potential integer
15 overflow [CVE-2014-4607,LMS-2014-06-16-1] is irrelevant anyway
16 because the function is never used on external data).
17 * Fixed a minor bug in exepack_fill.c that was unearthed by the minilzo
18 overflow check (the required buffer length information for the check
19 wasn't provided)
20 * Fixed incorrect logic in setting the ALLIGNORE flag (more specific
21 directory / file directives were ignored)
22 * Fix for tickets #358 (repetitive lstat warning about deleted
23 directory) and #359 (reporting of deleted/added top level directory)

41 suidcheck

43 - eliminate compiler warnings
