* | | Protect against DoS attacks, such as being described in CVE-2010-2632.marcel2012-12-011-22/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The changes were derived from what has been committed to NetBSD, with modifications. These are: 1. Preserve the existsing GLOB_LIMIT behaviour by including the number of matches to the set of parameters to limit. 2. Change some of the limits to avoid impacting normal use cases: GLOB_LIMIT_STRING - change from 65536 to ARG_MAX so that glob(3) can still provide a full command line of expanded names. GLOB_LIMIT_STAT - change from 128 to 1024 for no other reason than that 128 feels too low (it's not a limit that impacts the behaviour of the test program listed in CVE-2010-2632). GLOB_LIMIT_PATH - change from 1024 to 65536 so that glob(3) can still provide a fill command line of expanded names. 3. Protect against buffer overruns when we hit the GLOB_LIMIT_STAT or GLOB_LIMIT_READDIR limits. We append SEP and EOS to pathend in those cases. Return GLOB_ABORTED instead of GLOB_NOSPACE when we would otherwise overrun the buffer. This change also modifies the existing behaviour of glob(3) in case GLOB_LIMIT is specifies by limiting the *new* matches and not all matches. This is an important distinction when GLOB_APPEND is set or when the caller uses a non-zero gl_offs. Previously pre-existing matches or the value of gl_offs would be counted in the number of matches even though the man page states that glob(3) would return GLOB_NOSPACE when gl_matchc or more matches were found. The limits that cannot be circumvented are GLOB_LIMIT_STRING and GLOB_LIMIT_PATH all others can be crossed by simply calling glob(3) again and with GLOB_APPEND set. The entire description above applies only when GLOB_LIMIT has been specified of course. No limits apply when this flag isn't set! Obtained from: Juniper Networks, Inc
* | | In globextend(), take advantage of the fact that realloc(NULL, size) ismarcel2012-12-011-3/+2
| | | | | | | | | | | | | | | | | | equivalent to malloc(size). This eliminates the conditional expression used for calling either realloc() or malloc() when realloc() will do all the time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | free and clear the gl_pathv pointer in the glob_t structure. Such breaks the invariant of the glob_t structure, as stated in the comment right in front of the globextend() function. If gl_pathv was non-NULL, then gl_pathc was > 0. Making gl_pathv a NULL pointer without also setting gl_pathc to 0 is wrong. Since we otherwise don't free the memory associated with a glob_t in error cases, it's unlikely that this change will cause a memory leak that wasn't already there to begin with. Callers of glob(3) must call globfree(3) irrespective of whether glob(3) returned an error or not.

* | | libc: Allow setting close-on-exec in fopen/freopen/fdopen.jilles2012-11-304-2/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a new mode option 'e' that must follow any 'b', '+' and/or 'x' options. C11 is clear about the 'x' needing to follow 'b' and/or '+' and that is what we implement; therefore, require a strict position for 'e' as well. For freopen() with a non-NULL path argument and fopen(), the close-on-exec flag is set iff the 'e' mode option is specified. For freopen() with a NULL path argument and fdopen(), the close-on-exec flag is turned on if the 'e' mode option is specified and remains unchanged otherwise. Although the same behaviour for fopen() can be obtained by open(O_CLOEXEC) and fdopen(), this needlessly complicates the calling code. Apart from the ordering requirement, the new option matches glibc. PR: kern/169320
