Original advisory details:

  Andy Boothe discovered that the Networking component of OpenJDK 8 did not
  properly handle access under certain circumstances. An unauthenticated
  attacker could possibly use this issue to cause a denial of service.
  (CVE-2024-21208)

  It was discovered that the Hotspot component of OpenJDK 8 did not properly
  handle vectorization under certain circumstances. An unauthenticated
  attacker could possibly use this issue to access unauthorized resources
  and expose sensitive information. (CVE-2024-21210, CVE-2024-21235)

  It was discovered that the Serialization component of OpenJDK 8 did not
  properly handle deserialization under certain circumstances. An
  unauthenticated attacker could possibly use this issue to cause a denial
  of service. (CVE-2024-21217)

  It was discovered that the Hotspot component of OpenJDK 8 was not properly
  bounding certain UTF-8 strings, which could lead to a buffer overflow. An
  attacker could possibly use this issue to cause a denial of service or
  execute arbitrary code. This issue was only addressed in Ubuntu 16.04 LTS.
  (CVE-2024-21131)

  It was discovered that the Hotspot component of OpenJDK 8 could be made to
  run into an infinite loop. If an automated system were tricked into
  processing excessively large symbols, an attacker could possibly use this
  issue to cause a denial of service. This issue was only addressed in
  Ubuntu 16.04 LTS. (CVE-2024-21138)

  It was discovered that the Hotspot component of OpenJDK 8 did not properly
  perform range check elimination. An attacker could possibly use this issue
  to cause a denial of service, execute arbitrary code or bypass Java
  sandbox restrictions. This issue was only addressed in Ubuntu 16.04 LTS.
  (CVE-2024-21140)

  Yakov Shafranovich discovered that the Concurrency component of OpenJDK 8
  incorrectly performed header validation in the Pack200 archive format. An
  attacker could possibly use this issue to cause a denial of service. This
  issue was only addressed in Ubuntu 16.04 LTS. (CVE-2024-21144)

  Sergey Bylokhov discovered that OpenJDK 8 did not properly manage memory
  when handling 2D images. An attacker could possibly use this issue to
  obtain sensitive information. This issue was only addressed in Ubuntu
  16.04 LTS. (CVE-2024-21145)

  It was discovered that the Hotspot component of OpenJDK 8 incorrectly
  handled memory when performing range check elimination under certain
  circumstances. An attacker could possibly use this issue to cause a
  denial of service, execute arbitrary code or bypass Java sandbox
  restrictions. This issue was only addressed in Ubuntu 16.04 LTS.
  (CVE-2024-21147)

  It was discovered that the Hotspot component of OpenJDK 8 incorrectly
  handled certain exceptions with specially crafted long messages. An
  attacker could possibly use this issue to cause a denial of service.
  This issue was only addressed in Ubuntu 16.04 LTS. (CVE-2024-21011)

  Vladimir Kondratyev discovered that the Hotspot component of OpenJDK 8
  incorrectly handled address offset calculations in the C1 compiler. An
  attacker could possibly use this issue to cause a denial of service
  or execute arbitrary code. This issue was only addressed in Ubuntu
  16.04 LTS. (CVE-2024-21068)

  Yakov Shafranovich discovered that OpenJDK 8 did not properly manage
  memory in the Pack200 archive format. An attacker could possibly use this
  issue to cause a denial of service. This issue was only addressed in
  Ubuntu 16.04 LTS. (CVE-2024-21085)

  It was discovered that the Hotspot component of OpenJDK 8 incorrectly
  handled array accesses in the C2 compiler. An attacker could possibly use
  this issue to cause a denial of service or execute arbitrary code. This
  issue was only addressed in Ubuntu 16.04 LTS. (CVE-2024-21094)

  Yi Yang discovered that the Hotspot component of OpenJDK 8 incorrectly
  handled array accesses in the C1 compiler. An attacker could possibly
  use this issue to cause a denial of service, execute arbitrary code or
  bypass Java sandbox restrictions. This issue was only addressed in Ubuntu
  16.04 LTS. (CVE-2024-20918)

  It was discovered that the Hotspot component of OpenJDK 8 did not
  properly verify bytecode in certain situations. An attacker could
  possibly use this issue to bypass Java sandbox restrictions. This
  issue was only addressed in Ubuntu 16.04 LTS. (CVE-2024-20919)

  It was discovered that the Hotspot component of OpenJDK 8 had an
  optimization flaw when generating range check loop predicates. An attacker
  could possibly use this issue to cause a denial of service, execute
  arbitrary code or bypass Java sandbox restrictions. This issue was only
  addressed in Ubuntu 16.04 LTS. (CVE-2024-20921)

  Valentin Eudeline discovered that OpenJDK 8 incorrectly handled certain
  options in the Nashorn JavaScript subcomponent. An attacker could
  possibly use this issue to execute arbitrary code. This issue was only
  addressed in Ubuntu 16.04 LTS. (CVE-2024-20926)

  It was discovered that OpenJDK 8 could produce debug logs that contained
  private keys used for digital signatures. An attacker could possibly use
  this issue to obtain sensitive information. This issue was only addressed
  in Ubuntu 16.04 LTS. (CVE-2024-20945)

  Hubert Kario discovered that the TLS implementation in OpenJDK 8 had a
  timing side-channel and incorrectly handled RSA padding. A remote attacker
  could possibly use this issue to recover sensitive information. This
  issue was only addressed in Ubuntu 16.04 LTS. (CVE-2024-20952)
