SB2021090927 - SUSE update for java-1_7_0-openjdk

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Speculative Store Bypass (CVE-ID: CVE-2018-3639)

The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.

The weakness exists due to race conditions in CPU cache processing. A local attacker can conduct a side-channel attack to exploit a flaw in the speculative execution of Load and Store instructions to read privileged memory.

Note: the vulnerability is referred to as "Spectre variant 4".

2) Code Injection (CVE-ID: CVE-2021-2161)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation in the java.lang.ProcessBuilder API on the Windows platform. A remote attacker can manipulate the Process command line and execute arbitrary code on the target system.

3) 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.

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

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.

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

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.

6) Improper input validation (CVE-ID: CVE-2021-2432)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The vulnerability exists due to improper input validation within the JNDI component in Java SE. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.
