Remove typo'd commit
Fix bug 72788: Invalid memory access when database_object_handle is undefined. Also fix memory leak in dbh_free when using persistent PDO connections.
Also initialize buffer and buffer2 to NULL, which should fix bug #72039 (Use of uninitialised value on mssql_guid_string).
This only applies to 5.6, as we do not have mssql in 7.0 anymore
Before this patch, exif_process_IFD_in_MAKERNOTE() would return false, then causing the rest of the EXIF parsing to be interrupted. This is a regression from earlier which was most likely a part of a security fix for MAKERNOTE.
The new behavior is to instead of stopping to parse, to continue so we can still fetch data like thumbnail and GPS, thrus allowing yet unsupported formats to parse. If EXIF's debugging mode is enabled, a notice will display in case we do not match against a valid MAKERNOTE signature.
This should temporarily fix bug #72682 (exif_read_data() fails to read all data for some images) until I get around to debug it further.
(cherry picked from commit aabcb5481d)
Calling imagesetstyle() with an empty $styles array caused gdImageSetStyle()
to be called with `noOfPixels==0`, what could have lead to OOB reads.
Actually, this issue will be fixed in libgd, but to avoid issues when older
libgd is in use, we simply disallow passing an empty $styles array to
imagesetstyle(), what wouldn't serve a useful purpose anyway.
This reverts commit 2fba646837.
PCRE-8.39 throws weird valgrind backtraces on some systems, see
http://news.php.net/php.cvs/93494 . Those could be false positives
due to some changes in JIT, still i couldn't 100% ensure this.
Thus, better we continue to ship 8.38 bundled for now, and apply
patches, if needed.
This reverts commit 14d674442e.
I misread the discussion on the bug -- this is not the correct
fix. However the other proposed fix does not work either, so just
reverting for now.
Julian days < 347998 denote invalid Jewish calendar dates, so
cal_from_jd($jd, CAL_JEWISH) and jdmonthname($jd, CAL_MONTH_JEWISH) should
actually fail. For BC we don't yet let them though, but we fix the OOB read
that happens in this case, and we also adjust cal_from_jd()'s return value
to have empty strings for "abbrevdayname" and "dayname" instead of "Sun"/
"Sunday" and NULL for "dow" instead of 0, which doesn't make any sense.
