Description

This security bulletin contains information about 10 secuirty vulnerabilities.


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

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.


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

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.


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

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.


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

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.


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

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.


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

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.


7) Infinite loop (CVE-ID: CVE-2018-14368)

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 Bazaar protocol dissector to crash.


8) Improper input validation (CVE-ID: CVE-2018-14369)

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 HTTP2 protocol dissector to crash.


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

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 CoAP protocol dissector to crash.


10) Improper input validation (CVE-ID: CVE-2018-14370)

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 IEEE 802.11 protocol dissector to crash.
