[USN-5202-1] OpenJDK vulnerabilities

========================================================================== Ubuntu Security Notice USN-5202-1 December 17, 2021
openjdk-8, openjdk-lts vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 21.10 – Ubuntu 21.04 – Ubuntu 20.04 LTS – Ubuntu 18.04 LTS – Ubuntu 16.04 ESM
Summary:
Several security issues were fixed in OpenJDK.
Software Description: – openjdk-8: Open Source Java implementation – openjdk-lts: Open Source Java implementation
Details:
Varnavas Papaioannou discovered that the FTP client implementation in OpenJDK accepted alternate server IP addresses when connecting with FTP passive mode. An attacker controlling an FTP server that an application connects to could possibly use this to expose sensitive information (rudimentary port scans). This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 21.04. (CVE-2021-2341)
Markus Loewe discovered that OpenJDK did not properly handle JAR files containing multiple manifest files. An attacker could possibly use this to bypass JAR signature verification. This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 21.04. (CVE-2021-2369)
Huixin Ma discovered that the Hotspot VM in OpenJDK did not properly perform range check elimination in some situations. An attacker could possibly use this to construct a Java class that could bypass Java sandbox restrictions. This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 21.04. (CVE-2021-2388)
Asaf Greenholts discovered that OpenJDK preferred certain weak ciphers by default. An attacker could possibly use this to expose sensitive information. (CVE-2021-35550)
It was discovered that the Rich Text Format (RTF) Parser in OpenJDK did not properly restrict the amount of memory allocated in some situations. An attacker could use this to specially craft an RTF file that caused a denial of service. (CVE-2021-35556)
It was discovered that the Rich Text Format (RTF) Reader in OpenJDK did not properly restrict the amount of memory allocated in some situations. An attacker could use this to specially craft an RTF file that caused a denial of service. (CVE-2021-35559)
Markus Loewe discovered that the HashMap and HashSet implementations in OpenJDK did not properly validate load factors during deserialization. An attacker could use this to cause a denial of service (excessive memory consumption). (CVE-2021-35561)
It was discovered that the Keytool component in OpenJDK did not properly handle certificates with validity ending dates in the far future. An attacker could use this to specially craft a certificate that when imported could corrupt a keystore. (CVE-2021-35564)
Tristen Hayfield discovered that the HTTP server implementation in OpenJDK did not properly handle TLS session close in some situations. A remote attacker could possibly use this to cause a denial of service (application infinite loop). (CVE-2021-35565)
Chuck Hunley discovered that the Kerberos implementation in OpenJDK did not correctly report subject principals when using Kerberos Constrained Delegation. An attacker could possibly use this to cause incorrect Kerberos tickets to be used. (CVE-2021-35567)
it was discovered that the TLS implementation in OpenJDK did not properly handle TLS handshakes in certain situations where a Java application is acting as a TLS server. A remote attacker could possibly use this to cause a denial of service (application crash). (CVE-2021-35578)
it was discovered that OpenJDK did not properly restrict the amount of memory allocated when processing BMP images. An attacker could use this to specially craft a BMP image file that could cause a denial of service. (CVE-2021-35586)
It was discovered that the HotSpot VM in OpenJDK 8 did not properly perform validation of inner class index values in some situations. An attacker could use this to specially craft a class file that when loaded could cause a denial of service (Java VM crash). (CVE-2021-35588)
Artem Smotrakov discovered that the TLS implementation in OpenJDK used non- constant time comparisons during TLS handshakes. A remote attacker could use this to expose sensitive information. (CVE-2021-35603)
