Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Race condition

EUVDB-ID: #VU31891

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-15586

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The 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.

Mitigation

Install updates from vendor's website.

2) Infinite loop

EUVDB-ID: #VU45699

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-2020-16845

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The 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.

Mitigation

3) Input validation error

EUVDB-ID: #VU48480

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-28362

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in a number of math/big.Int methods (Div, Exp, DivMod, Quo, Rem, QuoRem, Mod, ModInverse, ModSqrt, Jacobi, and GCD). A remote attacker can pass large input data to the application, specifically as divisor or modulo argument larger than 3168 bits (on 32-bit architectures) or 6336 bits (on 64-bit architectures).

Mitigation

Install updates from vendor's website.

4) Incorrect calculation

EUVDB-ID: #VU50047

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2021-3114

CWE-ID: CWE-682 - Incorrect Calculation

Exploit availability: No

Description

The 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.

Mitigation

Install updates from vendor's website.
