CVE-2017-9937

Published: 26 June 2017

In LibTIFF 4.0.8, there is a memory malloc failure in tif_jbig.c. A crafted TIFF document can lead to an abort resulting in a remote denial of service attack.

Notes

AuthorNote
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.

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).
