Security Bulletin
This security bulletin contains information about 8 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU13051
Risk: High
CVSSv3.1: 9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2014-8146
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to cause Dos condition or execute arbitrary code on the target system.
The vulnerability exists due to heap-based buffer overflow when the resolveImplicitLevels function in common/ubidi.c in the Unicode Bidirectional Algorithm implementation in ICU4C does not properly track directionally isolated pieces of text. A remote unauthenticated attacker can supply specially crafted text file, trigger memory corruption and cause the service to crash or execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected packages.

2) Improper input validation
EUVDB-ID: #VU13052
Risk: High
CVSSv3.1: 9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2014-8147
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The vulnerability exists due to the resolveImplicitLevels function in common/ubidi.c in the Unicode Bidirectional Algorithm implementation in ICU4C uses an integer data type that is inconsistent with a header file. A remote unauthenticated attacker can supply specially crafted text file, trigger incorrect malloc followed by invalid free and cause the service to crash or execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected packages.

CVE-ID: CVE-2016-6293
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to the uloc_acceptLanguageFromHTTP function in common/uloc.cpp for C/C++ does not ensure that there is a '' character at the end of a certain temporary array. A remote unauthenticated attacker can supply a call with a long httpAcceptLanguage argument, trigger out-of-bounds read and cause the service to crash.
MitigationUpdate the affected packages.

4) Double free memory error
EUVDB-ID: #VU13054
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-14952
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to double free memory error in i18n/zonemeta.cpp in International Components for Unicode (ICU) for C/C++. A remote unauthenticated attacker can supply a ca specially crafted string, aka a "redundant UVector entry clean up function call" issue, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected packages.

5) Integer overflow
EUVDB-ID: #VU9588
Risk: Low
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-15422
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to integer overflow in ICU. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.

CVE-ID: CVE-2017-17484
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to stack-based buffer overflow when the ucnv_UTF8FromUTF8 function in ucnv_u8.cpp in International Components for Unicode (ICU) for C/C++ mishandles ucnv_convertEx calls for UTF-8 to UTF-8 conversion.
