Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Race condition (CVE-ID: CVE-2020-15586)

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.


2) Infinite loop (CVE-ID: CVE-2020-16845)

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.


3) Input validation error (CVE-ID: CVE-2020-28362)

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).


4) Improper input validation (CVE-ID: CVE-2021-2163)

The vulnerability allows a remote non-authenticated attacker to manipulate data.

The vulnerability exists due to improper input validation within the Libraries component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.


5) Incorrect calculation (CVE-ID: CVE-2021-3114)

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.


6) Improper Validation of Array Index (CVE-ID: CVE-2021-3121)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to improper validation of index array in plugin/unmarshal/unmarshal.go. A remote attacker can pass specially crafted data to the application and bypass implemented security restrictions, possibly leading to remote code execution.
