Description Tomas Hoger 2021-02-14 21:10:21 UTC 
IBM JDK 7 SR10 FP80 (7.0.10.80), 7.1 SR4 FP80 (7.1.4.80), 8 SR6 FP25 (8.0.6.25), and 11 SR10 (11.0.10.0) fix a flaw described by upstream as:

Eclipse OpenJ9 is vulnerable to a stack-based buffer overflow when the virtual machine or JNI natives are converting from UTF-8 characters to platform encoding. By sending an overly long string, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
