CVE-2017-11628

In PHP before 5.6.31, 7.x before 7.0.21, and 7.1.x before 7.1.7, a stack-based buffer overflow in the zend_ini_do_op() function in Zend/zend_ini_parser.c could cause a denial of service or potentially allow executing code. NOTE: this is only relevant for PHP applications that accept untrusted input (instead of the system's php.ini file) for the parse_ini_string or parse_ini_file function, e.g., a web application for syntax validation of php.ini directives.

This update for php7 fixes the following issues:

• CVE-2016-10397: parse_url() can be bypassed to return fake host. (bsc#1047454)
• CVE-2017-11142: Remoteattackers could cause a CPU consumption denial of service attack by injectinglong form variables, related to main/php_variables. (bsc#1048100)
• CVE-2017-11144: The opensslextension PEM sealing code did not check the return value of the OpenSSL sealingfunction, which could lead to a crash. (bsc#1048096)
• CVE-2017-11145: Lack of bounds checks in timelib_meridian coud lead to information leak. (bsc#1048112)
• CVE-2017-11146: Lack of bounds checks in timelib_meridian parse code could lead to information leak. (bsc#1048111)
• CVE-2017-11147: The PHAR archive handler could beused by attackers supplying malicious archive files to crash the PHP interpreteror potentially disclose information. (bsc#1048094)
• CVE-2017-11628: Stack-base dbuffer overflow in zend_ini_do_op() could lead to denial of service (bsc#1050726)
• CVE-2017-7890: Buffer over-read from unitialized data in gdImageCreateFromGifCtx function could lead to denial of service (bsc#1050241)
• CVE-2016-5766: Integer Overflow in _gd2GetHeader() resulting in heap overflow could lead to denial of service or code execution (bsc#986386)

Other fixes:

• Soap Request with References (bsc#1053645)
• php7-pear should explicitly require php7-pear-Archive_Tar otherwise this dependency must be declared in every php7-pear-* package explicitly. [bnc#1052389]

• CVE-2017-7890: Buffer over-read from unitialized data in gdImageCreateFromGifCtx function could lead to denial of service (bsc#1050241)

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).

It was discovered that the PHP opcache created keys for files it cached based on their filepath. A local attacker could possibly use this issue in a shared hosting environment to obtain sensitive information. This issue only affected Ubuntu 14.04 LTS. (CVE-2015-8994)

It was discovered that the PHP URL parser incorrectly handled certain URI components. A remote attacker could possibly use this issue to bypass hostname-specific URL checks. This issue only affected Ubuntu 14.04 LTS. (CVE-2016-10397)
