The bd generates a core file and restarts.

- ASM running on BIG-IP version 15.1.5.1 or 15.1.6. Other versions are not affected. - Content profile is configured to check attack signatures.
Set the internal parameter disable_second_extra_normalization to 1 and restart ASM by executing: /usr/share/ts/bin/add_del_internal add disable_second_extra_normalization 1 bigstart restart asm Note: This relaxes matching of attack signatures for some cases.
Fixed a bd crash. As mentioned in Conditions field, there are only two official software versions, version 15.1.5.1 and version 15.1.6, that are affected by this bug. This bug was fixed on other major release branches (17.0.x, 16.1.x, 14.1.x, and 13.1.x) before publishing any affected versions to the field, thus this bug appears as fixed with those major releases, but there are actually no affected official versions.
