Description

This security bulletin contains information about 9 secuirty vulnerabilities.

1) Improper input validation (CVE-ID: CVE-2018-11354)

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)

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) Null pointer dereference (CVE-ID: CVE-2018-11356)

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

The weakness exists in epan/dissectors/packet-dns.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 DNS dissector to crash.

4) Resource exhaustion (CVE-ID: CVE-2018-11357)

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.

5) Use-after-free error (CVE-ID: CVE-2018-11358)

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.

6) Null pointer dereference (CVE-ID: CVE-2018-11359)

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.

7) Buffer overflow (CVE-ID: CVE-2018-11360)

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.

8) Buffer overflow (CVE-ID: CVE-2018-11361)

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.

9) Buffer over-read (CVE-ID: CVE-2018-11362)

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.
