Summary

Several security issues were fixed in OpenJDK 11.

Software Description:

- openjdk-lts: Open Source Java implementation

Details:

It was discovered that the Hotspot component of OpenJDK 11 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 11 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 11 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)
