Open Source Vulnerabilities SUSE-SU-2017:2522-1

This update for php53 fixes the several issues. These security issues were fixed: - CVE-2017-12933: The finish_nested_data function in ext/standard/var_unserializer.re was prone to a buffer over-read while unserializing untrusted data. Exploitation of this issue could have had an unspecified impact on the integrity of PHP (bsc#1054430). - CVE-2017-11628: Stack-based buffer overflow in the zend_ini_do_op() function in Zend/zend_ini_parser.c could have caused a denial of service or potentially allowed executing code (bsc#1050726). - CVE-2017-7890: The GIF decoding function gdImageCreateFromGifCtx in the GD Graphics Library did not zero colorMap arrays use. A specially crafted GIF image could use the uninitialized tables to read ~700 bytes from the top of the stack, potentially disclosing sensitive information (bsc#1050241). - CVE-2016-5766: Integer overflow in the _gd2GetHeader in the GD Graphics Library (aka libgd) allowed remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via crafted chunk dimensions in an image (bsc#986386). - CVE-2017-11145: An error in the date extension's timelib_meridian parsing code could have been used by attackers able to supply date strings to leak information from the interpreter, related to ext/date/lib/parse_date.c out-of-bounds reads affecting the php_parse_date function (bsc#1048112). - CVE-2017-11146: Lack of bounds checks in timelib_meridian parse code could have lead to information leak [bsc#1048111] - CVE-2016-10397: Incorrect handling of various URI components in the URL parser could have been used by attackers to bypass hostname-specific URL checks (bsc#1047454). - CVE-2017-11147: The PHAR archive handler could have been used by attackers supplying malicious archive files to crash the PHP interpreter or potentially disclose information due to a buffer over-read in the phar_parse_pharfile function (bsc#1048094). - CVE-2017-11144: The openssl extension PEM sealing code did not check the return value of the OpenSSL sealing function, which could have lead to a crash of the PHP interpreter (bsc#1048096).
