Description
This security bulletin contains information about 10 vulnerabilities.
1) Incorrect calculation (CVE-ID: CVE-2016-10158)
CWE-ID: CWE-682 - Incorrect Calculation
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the exif_convert_any_to_int function in ext/exif/exif.c due to numeric errors. A remote attacker can submit specially crafted EXIF data that triggers an attempt to divide the minimum representable negative integer by -1 and cause the service to crash.
2) Integer overflow (CVE-ID: CVE-2016-10159)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the phar_parse_pharfile function in ext/phar/phar.c due to integer overflow. A remote attacker can submit a truncated manifest entry in a PHAR archive and cause the service to crash.
3) Off-by-one error (CVE-ID: CVE-2016-10160)
CWE-ID: CWE-193 - Off-by-one Error
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists in the phar_parse_pharfile function in ext/phar/phar.c due to off-by-one error. A remote attacker can submit a specially crafted PHAR archive with an alias mismatch and cause the service to crash or execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
4) Buffer over-read (CVE-ID: CVE-2016-10161)
CWE-ID: CWE-126 - Buffer over-read
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the object_common1 function in ext/standard/var_unserializer.c due to buffer over-read. A remote attacker can submit specially crafted serialized data that is mishandled in a finish_nested_data call and cause the service to crash.
5) NULL pointer dereference (CVE-ID: CVE-2016-10162)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the php_wddx_pop_element function in ext/wddx/wddx.c due to NULL pointer dereference. A remote attacker can submit an inapplicable class name in a wddxPacket XML document, leading to mishandling in a wddx_deserialize call, and cause the service to crash.
6) Use-after-free error (CVE-ID: CVE-2016-7479)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to resizing the 'properties' hash table of a serialized object during the unserialization process. A remote attacker can trigger use-after-free error and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
7) Use-after-free (CVE-ID: CVE-2016-9137)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to use-after-free error in the CURLFile implementation in ext/curl/curl_file.c in PHP before 5.6.27 and 7.x before 7.0.12. A remote attacker can cause a denial of service via specially crafted serialized data that is mishandled during __wakeup processing.
8) Out-of-bounds read (CVE-ID: CVE-2016-9935)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the php_wddx_push_element function in ext/wddx/wddx.c due to out-of-bounds read. A remote attacker can submit an empty boolean element in a wddxPacket XML document and cause the service to crash.
9) Use-after-free error (CVE-ID: CVE-2016-9936)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the unserialize implementation in ext/standard/var.c due to use-after-free error. A remote attacker can submit crafted serialized data and cause the service to crash.
10) Integer overflow (CVE-ID: CVE-2017-5340)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists in zend/zend_hash.c due to mishandling certain cases that require large array allocations. A remote attacker can submit specially crafted serialized data and cause the service to crash or execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
