Security Bulletin

This security bulletin contains information about 6 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

Description

The 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.

Mitigation

Update the affected packages.

2) Information disclosure

EUVDB-ID: #VU11789

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2017-7890

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information.

The weakness exists in the GIF decoding function gdImageCreateFromGifCtx in gd_gif_in.c due to it does not zero colorMap arrays before use.

3) 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

Description

The 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.

4) 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

Description

The 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.

Mitigation

Update the affected packages.

5) 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

Description

The 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.

Mitigation

Update the affected packages.

CVE-ID: CVE-2017-9224

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The 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.

Mitigation

Update the affected packages.
