Description
This security bulletin contains information about 3 vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2020-11647)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing data in BACapp dissector. A remote attacker can send specially crafted data via the network, trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Resource exhaustion (CVE-ID: CVE-2020-13164)
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 perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in NFS dissector. A remote attacker can inject a malformed packet onto the wire or trick a victim to read a malformed packet trace file and perform a denial of service (DoS) attack.
3) Infinite loop (CVE-ID: CVE-2020-15466)
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:P/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the GVCP dissector. A remote attacker can pass specially crafted packet trace file to the application, consume all available system resources and cause denial of service conditions.
