  script_tag(name:"insight", value:"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 ... [Please see the references for more information on the vulnerabilities]");
