Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) 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.
Install update from vendor's website.

2) 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.
