Description

This security bulletin contains information about 10 vulnerabilities.


1) Infinite loop (CVE-ID: CVE-2018-14339)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to a flaw when handling malicious input. A remote attacker can inject a malformed packet onto the wire or trick the victim into reading a malformed packet trace file, trigger infinite loop and cause the MMSE dissector to crash.


2) Improper input validation (CVE-ID: CVE-2018-14340)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to a flaw when handling malicious input. A remote attacker can inject a malformed packet onto the wire or trick the victim into reading a malformed packet trace file and cause the dissectors that support zlib decompression to crash.


3) Infinite loop (CVE-ID: CVE-2018-14341)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to an infinite loop when handling malicious input. A remote attacker can inject a malformed packet onto the wire or trick the victim into reading a malformed packet trace file, consume excessive CPU resources and cause the DICOM dissector to crash.


4) Resource exhaustion (CVE-ID: CVE-2018-14342)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to a flaw when handling malicious input. A remote attacker can inject a malformed packet onto the wire or trick the victim into reading a malformed packet trace file,  consume excessive CPU resources and cause the BGP dissector to crash.


5) Improper input validation (CVE-ID: CVE-2018-14343)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to a flaw when handling malicious input. A remote attacker can inject a malformed packet onto the wire or trick the victim into reading a malformed packet trace file and cause the ASN.1 BER dissector to crash.


6) Improper input validation (CVE-ID: CVE-2018-14344)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to a flaw when handling malicious input. A remote attacker can inject a malformed packet onto the wire or trick the victim into reading a malformed packet trace file and cause the ISMP dissector to crash.


7) Improper input validation (CVE-ID: CVE-2018-14367)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
