Notes

mdeslaur

reported in libtiff, but issue lies in jbigkit as of 2018-03-22, no fix available this is a DoS only and is caused by the fact that jbigkit handles failed memory allocations with abort(). (See checked_malloc()). Fixing this properly would likely require changing the library ABI.

ccdm94

commit bc3293299b was released in 2020, and it seems to be the commit that fixes this issue, according to the commit message and according to tests made with the commit applied to jbigkit (the error no longer occurs once this fix is applied).
