USN-6660-1: OpenJDK 11 vulnerabilities

Read Time:1 Minute, 5 Second

Yi Yang discovered that the Hotspot component of OpenJDK 11 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. (CVE-2024-20918)

It was discovered that the Hotspot component of OpenJDK 11 did not
properly verify bytecode in certain situations. An attacker could
possibly use this issue to bypass Java sandbox restrictions.
(CVE-2024-20919)

It was discovered that the Hotspot component of OpenJDK 11 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. (CVE-2024-20921)

Valentin Eudeline discovered that OpenJDK 11 incorrectly handled certain
options in the Nashorn JavaScript subcomponent. An attacker could
possibly use this issue to execute arbitrary code. (CVE-2024-20926)

It was discovered that OpenJDK 11 could produce debug logs that contained
private keys used for digital signatures. An attacker could possibly use
this issue to obtain sensitive information. (CVE-2024-20945)

Hubert Kario discovered that the TLS implementation in OpenJDK 11 had a
timing side-channel and incorrectly handled RSA padding. A remote attacker
could possibly use this issue to recover sensitive information.
