Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU7345
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-9224
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information.
The weakness exists in the mbstring due to stack out-of-bounds read in match_at() during regular expression searching. A remote attacker can trigger a logical error involving order of validation and access in match_at() and read arbitrary files on the system.
Successful exploitation of the vulnerability results in information disclosure.
Update the affected package php to version 5.6.31.

2) Heap-out-of-bounds write
EUVDB-ID: #VU7346
Risk: High
CVSSv4.0: 8.1 [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/E:U/U:Amber]
CVE-ID: CVE-2017-9226
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code.
The weakness exists in the mbstring due to heap out-of-bounds write or read occurs in next_state_val() during regular expression compilation. A remote attacker can supply a malformed regular expression containing an octal number in the form of '\700', trigger
out-of-bounds write memory corruption and execute arbitrary code with web server privileges.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected package php to version 5.6.31.

3) Out-of-bounds read
EUVDB-ID: #VU7347
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-9227
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information.
The weakness exists in the mbstring due to an error in handling of reg->dmin in forward_search_range(). A remote attacker can trigger stack out-of-bounds read in mbc_enc_len() during regular expression searching and read arbitrary files on the system.
Successful exploitation of the vulnerability results in information disclosure.

4) Heap-out-of-bounds write
EUVDB-ID: #VU7348
Risk: High
CVSSv4.0: 8.1 [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/E:U/U:Amber]
CVE-ID: CVE-2017-9228
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code.
The weakness exists in the mbstring due to heap out-of-bounds write in bitset_set_range() during regular expression compilation due to incorrect state transition in parse_char_class(). A remote attacker can trigger out-of-bounds write memory corruption and execute arbitrary code with web server privileges.
Successful exploitation of the vulnerability may result in system compromise.

5) Null pointer dereference
EUVDB-ID: #VU7349
Risk: Low
CVSSv4.0: 2.7 [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/E:U/U:Clear]
CVE-ID: CVE-2017-9229
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition.
The weakness exists in the mbstring due to an error in handling of reg->dmin in forward_search_range(). A remote attacker can trigger SIGSEGV in left_adjust_char_head() during regular expression compilation, cause NULL pointer dereference and the application to crash.
Successful exploitation of the vulnerability results in denial of service.
