An issue was discovered in Yubico libykpiv before 2.1.0. An attacker can trigger an incorrect free() in the ykpiv_util_generate_key() function in lib/util.c through incorrect error handling code. This could be used to cause a denial of service attack.

Comment 2 Wolfgang Frisch 2021-07-26 16:54:23 UTC

openSUSE:Factory is already fixed.
SUSE:SLE-15-SP1:Update needs an update.

Comment 3 Wolfgang Frisch 2021-11-18 18:24:03 UTC

Not LTSS-worthy.
