Description
This security bulletin contains information about 7 vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2018-16056)
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:P/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to the epan/dissectors/packet-btatt.c source code file of the affected software does not verify that a dissector for a specific universally unique identifier (UUID) exists. A remote attacker can inject a malformed packet into a network, to be processed by the affected application, or trick the victim into opening a malicious packet trace file and cause the Bluetooth ATT dissector component to crash.
2) Memory corruption (CVE-ID: CVE-2018-16057)
CWE-ID: CWE-119 - Memory corruption
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:P/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to boundary error in the ieee80211_radiotap_iterator_next() function, as defined in the epan/dissectors/packet-ieee80211-radiotap-iter.c source code file. A remote attacker can inject a malformed packet into a network, to be processed by the affected application, or trick the victim into opening a malicious packet trace file and cause the Radiotap dissector component to crash.
3) Improper input validation (CVE-ID: CVE-2018-16058)
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:P/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to the epan/dissectors/packet-btavdtp.c source code file of the affected software improperly initializes a data structure. A remote attacker can inject a malformed packet into a network, to be processed by the affected application, or trick the victim into opening a malicious packet trace file and cause the AVDTP dissector component to crash.
4) Improper input validation (CVE-ID: CVE-2018-18227)
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:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can inject a malformed packet into a network, to be processed by the affected application, or trick the victim into opening a malicious packet trace file and cause the MS-WSP dissector component to crash.
5) Memory leak (CVE-ID: CVE-2018-18226)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: 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
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The vulnerability exists due to memory leak in the Steam IHS Discovery dissector when handling malicious input. A remote attacker can inject a malformed packet into a network, to be processed by the affected application, or trick the victim into opening a malicious packet trace file and gain access to arbitrary data.
6) Improper input validation (CVE-ID: CVE-2018-18225)
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:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can inject a malformed packet into a network, to be processed by the affected application, or trick the victim into opening a malicious packet trace file and cause the CoAP dissector component to crash.
7) Improper input validation (CVE-ID: CVE-2018-12086)
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:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can inject a malformed packet into a network, to be processed by the affected application, or trick the victim into opening a malicious packet trace file and cause the OpcUa dissector component to crash.
