This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU29673
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-7919

EUVDB-ID: #VU31891
Risk: Medium
CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-15586
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a race condition in some net/http servers, as demonstrated by the httputil.ReverseProxy Handler. A remote attacker can exploit the race and cause a denial of service condition on the target system.
MitigationUpdate golang-1.11 package to version 1.11.6-1+deb10u4.

EUVDB-ID: #VU45699
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-16845
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in "ReadUvarint" and "ReadVarint" in "encoding/binary". A remote attacker can consume all available system resources and cause denial of service conditions.
MitigationUpdate golang-1.11 package to version 1.11.6-1+deb10u4.

EUVDB-ID: #VU50047
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-3114
CWE-ID:
CWE-682 - Incorrect Calculation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to incorrect calculation performed by the application in "crypto/elliptic/p224.go". A remote attacker can generate incorrect outputs, related to an underflow of the lowest limb during the final complete reduction in the P-224 field.
MitigationUpdate golang-1.11 package to version 1.11.6-1+deb10u4.
