CVE-2017-11147

In PHP before 5.6.30 and 7.x before 7.0.15, the PHAR archive handler could be 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 in ext/phar/phar.c.

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)
