Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU9595
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-3738
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists due to buffer overflow in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. A remote attacker can cause the server to share the DH1024 private key among multiple clients and perform attack on TLS.
Update the affected package openssl to version 1.1.0.h-1.
Vulnerable software versionsArch Linux: All versions
External linkshttp://security.archlinux.org/advisory/ASA-201804-2
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) Resource exhaustion
EUVDB-ID: #VU11294
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-0739
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to excessive stack memory consumption. A remote attacker can cause the service to crash.
Update the affected package openssl to version 1.1.0.h-1.

3) Information disclosure
EUVDB-ID: #VU2972
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2016-0701
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists due to DH_check_pub_key() function in crypto/dh/dh_check.c in OpenSSL 1.0.2
before 1.0.2f does not ensure that prime numbers are appropriate for
Diffie-Hellman (DH) key exchange, which makes it easier for remote
attackers to discover a private DH exponent by making multiple
handshakes with a peer that chose an inappropriate number, as
demonstrated by a number in an X9.42 file.
Update the affected package openssl to version 1.1.0.h-1.
