Description
This security bulletin contains information about 3 vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2020-6058)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the "decode_cnt" function when processing SNMP packets. A remote attacker can send a specially crafted SNMP request, trigger out-of-bounds read error, read contents of memory on the system and cause a denial of service (DoS) condition.
2) Stack-based buffer overflow (CVE-ID: CVE-2020-6060)
CWE-ID: CWE-121 - Stack-based buffer overflow
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:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when the affected system handles multiple connections. A remote unauthenticated attacker can use a specially timed sequence of SNMP connections, trigger stack-based buffer overflow and cause a denial of service condition on the target system.
3) Out-of-bounds read (CVE-ID: CVE-2020-6059)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the "decode_int" function when processing SNMP packets. A remote attacker can send a specially crafted SNMP request, trigger out-of-bounds read error, read contents of memory on the system and cause a denial of service (DoS) condition.
