In IJG JPEG (aka libjpeg) from version 8 through 9c, jdhuff.c has an out-of-bounds array read for certain table pointers.
Notes
| Author | Note |
|---|---|
| mdeslaur | patch in libjpeg9 9d appears to be: - entropy->ac_cur_tbls[blkn] = entropy->ac_derived_tbls[compptr->ac_tbl_no]; + entropy->ac_cur_tbls[blkn] = /* AC needs no table when not present */ + cinfo->lim_Se ? entropy->ac_derived_tbls[compptr->ac_tbl_no] : NULL; per upstream libjpeg-turbo bug, libjpeg-turbo is not vulnerable to this issue |
| ccdm94 | due to the same reasoning provided by the libjpeg-turbo upstream in issue https://github.com/libjpeg-turbo/libjpeg-turbo/issues/445, it is safe to assume that libjpeg6b is also not vulnerable to this. |
