Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU24891
Risk: High
CVSSv4.0: 6.7 [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]
CVE-ID: CVE-2020-6058
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe 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.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Stack-based buffer overflow
EUVDB-ID: #VU24893
Risk: Medium
CVSSv4.0: 6.6 [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]
CVE-ID: CVE-2020-6060
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe 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.
