Description
This security bulletin contains information about 9 vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2018-11354)
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 insufficient validation of user-supplied input. A remote attacker can inject a malformed packet onto the wire or convince someone to read a malformed packet trace file and cause the IEEE 1905.1a dissector to crash.
2) Buffer overflow (CVE-ID: CVE-2018-11355)
CWE-ID: CWE-120 - Buffer overflow
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 buffer overflow when handling malicious input. 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 RTCP dissector to crash.
3) Resource exhaustion (CVE-ID: CVE-2018-11357)
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 in epan/tvbuff.c due to improper validation of user-supplied input. A remote attacker can inject a malformed packet onto the wire or convince someone to read a malformed packet trace file, trigger resource exhaustion and cause the LTP dissector and other dissectors to crash.
4) Use-after-free error (CVE-ID: CVE-2018-11358)
CWE-ID: CWE-416 - Use After Free
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-q931.c due to use-after-free memory error. 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 Q.931 dissector and other dissectors to crash.
5) Null pointer dereference (CVE-ID: CVE-2018-11359)
CWE-ID: CWE-476 - NULL Pointer Dereference
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/proto.c due to NULL pointer dereference. A remote attacker can inject a malformed packet onto the wire or convince someone to read a malformed packet trace file and cause the RRC dissector and other dissectors to crash.
6) Buffer overflow (CVE-ID: CVE-2018-11360)
CWE-ID: CWE-120 - Buffer overflow
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-gsm_a_dtap.c due to off-by-one error. A remote attacker can inject a malformed packet onto the wire or convince someone to read a malformed packet trace file, trigger buffer overflow and cause the GSM A DTAP dissector to crash.
7) Buffer overflow (CVE-ID: CVE-2018-11361)
CWE-ID: CWE-120 - Buffer overflow
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/crypt/dot11decrypt.c due to buffer overflow during FTE processing in Dot11DecryptTDLSDeriveKey. 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 IEEE 802.11 protocol dissector to crash.
8) 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.
9) Null pointer dereference (CVE-ID: CVE-2018-11356)
CWE-ID: CWE-476 - NULL Pointer Dereference
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.
