Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Use of a broken or risky cryptographic algorithm
EUVDB-ID: #VU17860
Risk: Low
CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2019-1559
CWE-ID:
CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to decrypt sensitive information.
The vulnerability exists due to the way an application behaves, when it receives a 0-byte record with invalid padding compared to the record with an invalid MAC, which results in padding oracle. A remote attacker can decrypt data.
Successful exploitation of the vulnerability requires that the application is using "non-stitched" ciphersuites and calls SSL_shutdown() twice (first, via a BAD_RECORD_MAC and again via a CLOSE_NOTIFY).Mitigation

No. We are not aware of malware exploiting this vulnerability.
2) Stack-based buffer overflow
EUVDB-ID: #VU17456
Risk: High
CVSSv4.0: 8.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]
CVE-ID: CVE-2019-3822
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The vulnerability exists due to the NT LAN Manager (NTLM) Curl_auth_create_ntlm_type3_message function creates an outgoing NTLM type-3 header and generates the request HTTP header contents based on previously received data. A remote unauthenticated attacker can send very large ‘nt response’ output data, that has been extracted from a previous NTLMv2 header that was provided by a malicious or broken HTTP server, trigger stack-based buffer overflow and cause the service to crash or execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
