USN-6932-1: OpenJDK 21 vulnerabilities

Read Time:1 Minute, 3 Second

It was discovered that the Hotspot component of OpenJDK 21 was not properly
performing bounds when handling 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. (CVE-2024-21131)

It was discovered that the Hotspot component of OpenJDK 21 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. (CVE-2024-21138)

It was discovered that the Hotspot component of OpenJDK 21 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. (CVE-2024-21140)

Sergey Bylokhov discovered that OpenJDK 21 did not properly manage memory
when handling 2D images. An attacker could possibly use this issue to
obtain sensitive information. (CVE-2024-21145)

It was discovered that the Hotspot component of OpenJDK 21 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. (CVE-2024-21147)
