Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) NULL pointer dereference
EUVDB-ID: #VU20385
Risk: Low
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2019-10097
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when processing PROXY header within the mod_remoteip. A remote attacker that controls a trusted proxy server can send a specially crafted PROXY header, trigger stack overflow and perform a denial of service (DoS) attack.

No. We are not aware of malware exploiting this vulnerability.
2) NULL pointer dereference
EUVDB-ID: #VU27061
Risk: Medium
CVSSv4.0: 7.7 [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:P/U:Green]
CVE-ID: CVE-2020-1967
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the SSL_check_chain() function during or after a TLS 1.3 handshake. A remote attacker can send an invalid or unrecognised signature algorithm and perform a denial of service (DoS) attack.

3) Heap-based buffer overflow
EUVDB-ID: #VU21059
Risk: Medium
CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2019-5482
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the tftp_receive_packet() function when processing TFTP data. A remote attacker can send specially crafted TFTP response to the vulnerable curl client, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
