Description

This security bulletin contains information about 5 vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2021-2341)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 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


The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The vulnerability exists due to improper input validation within the Networking component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.


2) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2021-2369)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to an error in JAR validation implementation. A remote attacker can modify the signed JAR file in a way it will be considered as signed.


3) Infinite loop (CVE-ID: CVE-2020-28928)

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

CVSSv4: 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


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

The vulnerability exists due to infinite loop within the wcsnrtombs() function in musl libc. A remote attacker can consume all available system resources and cause denial of service conditions.


4) Improper input validation (CVE-ID: CVE-2021-2388)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The vulnerability exists due to improper input validation within the Hotspot component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.


5) Improper input validation (CVE-ID: CVE-2021-29921)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 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:U/U:Amber


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The vulnerability exists due to improper input validation within the Python interpreter and runtime (CPython) component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
