Description
This security bulletin contains information about 7 vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2018-7418)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to boundary error in epan/dissectors/packet-sigcomp.c when extraction of the length value. A remote attacker can cause the SIGCOMP dissector to crash.
2) Buffer over-read (CVE-ID: CVE-2018-11362)
CWE-ID: CWE-126 - Buffer over-read
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 in epan/dissectors/packet-ldss.c due to buffer over-read upon encountering a missing '' character. A remote attacker can inject a malformed packet onto the wire or convince someone to read a malformed packet trace file, trigger memory corruption and cause the LDSS dissector to crash.
3) 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 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) 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 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.
5) Infinite loop (CVE-ID: CVE-2018-14368)
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 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.
6) 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.
7) Infinite loop (CVE-ID: CVE-2018-19622)
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:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to infinite loop when handling 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 MMSE dissector to crash.
