Last modified: 2019-04-11 19:23:38 CEST
+++ This bug was initially created as a clone of Bug #41479 +++ Upstream Debian package version 5.4.45-0+deb7u3 fixes these issues: * The file_check_mem function in funcs.c in file before 5.23, as used in the Fileinfo component in PHP before 5.5.34, mishandles continuation-level jumps, which allows context-dependent attackers to cause a denial of service (buffer overflow and application crash) or possibly execute arbitrary code via a crafted magic file (CVE-2015-8865) * libxml_disable_entity_loader setting is shared between threads ext/libxml/libxml.c in PHP before 5.5.22, when PHP-FPM is used, does not isolate each thread from libxml_disable_entity_loader changes in other threads, which allows remote attackers to conduct XML External Entity (XXE) and XML Entity Expansion (XEE) attacks via a crafted XML document, a related issue to CVE-2015-5161 (CVE-2015-8866). * main/php_open_temporary_file.c in PHP before 5.5.28 does not ensure thread safety, which allows remote attackers to cause a denial of service (race condition and heap memory corruption) by leveraging an application that performs many temporary-file accesses (CVE-2015-8878). * The odbc_bindcols function in ext/odbc/php_odbc.c in PHP before 5.6.12 mishandles driver behavior for SQL_WVARCHAR columns, which allows remote attackers to cause a denial of service (application crash) in opportunistic circumstances by leveraging use of the odbc_fetch_array function to access a certain type of Microsoft SQL Server table (CVE-2015-8879). * Integer overflow in the php_raw_url_encode function in ext/standard/url.c in PHP before 5.5.34 allows remote attackers to cause a denial of service (application crash) via a long string to the rawurlencode function (CVE-2016-4070). * Format string vulnerability in the php_snmp_error function in ext/snmp/snmp.c in PHP before 5.5.34 allows remote attackers to execute arbitrary code via format string specifiers in an SNMP::get call (CVE-2016-4071). * The Phar extension in PHP before 5.5.34 allows remote attackers to execute arbitrary code via a crafted filename, as demonstrated by mishandling of \0 characters by the phar_analyze_path function in ext/phar/phar.c (CVE-2016-4072). * Multiple integer overflows in the mbfl_strcut function in ext/mbstring/libmbfl/mbfl/mbfilter.c in PHP before 5.5.34 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted mb_strcut call (CVE-2016-4073). * The phar_make_dirstream function in ext/phar/dirstream.c in PHP before 5.6.18 mishandles zero-size ././@LongLink files, which allows remote attackers to cause a denial of service (uninitialized pointer dereference) or possibly have unspecified other impact via a crafted TAR archive (CVE-2016-4343). * The bcpowmod function in ext/bcmath/bcmath.c in PHP before 5.5.35 accepts a negative integer for the scale argument, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted call (CVE-2016-4537). * The xml_parse_into_struct function in ext/xml/xml.c in PHP before 5.5.35 allows remote attackers to cause a denial of service (buffer under-read and segmentation fault) or possibly have unspecified other impact via crafted XML data in the second argument, leading to a parser level of zero (CVE-2016-4539). * The grapheme_strpos function in ext/intl/grapheme/grapheme_string.c in PHP before 5.5.35 allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a negative offset (CVE-2016-4540, CVE-2016-4541). * The exif_process_* function in ext/exif/exif.c in PHP before 5.5.35 does not validate IFD sizes, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via crafted header data (CVE-2016-4542, CVE-2016-4543, CVE-2016-4544).
* CVE-2016-5093.patch Absence of null character causes unexpected zend_string length and leaks heap memory. The test script uses locale_get_primary_language to reach get_icu_value_internal but there are some other functions that also trigger this issue: locale_canonicalize, locale_filter_matches, locale_lookup, locale_parse * CVE-2016-5094.patch don't create strings with lengths outside int range * CVE-2016-5095.patch similar to CVE-2016-5094 don't create strings with lengths outside int range * CVE-2016-5096.patch int/size_t confusion in fread * CVE-TEMP-bug-70661.patch bug70661: Use After Free Vulnerability in WDDX Packet Deserialization * CVE-TEMP-bug-70728.patch bug70728: Type Confusion Vulnerability in PHP_to_XMLRPC_worker() * CVE-TEMP-bug-70741.patch bug70741: Session WDDX Packet Deserialization Type Confusion Vulnerability * CVE-TEMP-bug-70480-raw.patch bug70480: php_url_parse_ex() buffer overflow read For Debian 7 "Wheezy", these problems have been fixed in version 5.4.45-0+deb7u4.
That "bug70480" above is now known as CVE-2016-6288: * The php_url_parse_ex function in ext/standard/url.c in PHP before 5.5.38 allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via vectors involving the smart_str data type. (CVE-2016-6288)
