| Patch | Description | Author | Forwarded | Bugs | Origin | Last update |
|---|---|---|---|---|---|---|
| only_export_decoder_api.patch | Only export symbols defined in the decoder API. The encoder API is not final yet, so upstream exports all symbols to make development easier. For packaging we only want to expose the public API. |

| disable_tools.patch | Disable building of some internal tools that no longer link because internal symbols are no longer exported. | Joachim Bauch <bauch@struktur.de> | no | |||
| reject_reference_pics_from_different_sps.patch | [PATCH] Try to mitigate asan failures. See #345 for my analysis and details (This PR is just for discussion.) (The CVE references are obtained from the Debian security tracker, which links the issues.) This makes the following POCs stop failing: - poc3 (#337) - poc7-1 (#341) CVE-2022-43239 (note: does NOT fix poc7-2) - poc8-2, poc8-3, poc8-4 (#342) CVE-2022-43244 (note: does NOT fix poc8-1) - poc11-1, poc11-2 (#345) CVE-2022-43249 - poc12 (#346) - poc13 (#347) CVE-2022-43252 - poc16 (#350) |

| use_sps_from_the_image.patch | [PATCH] Use the sps from the image (as e.g mc_chroma is using the sps to determine picture properties, like pic_width_in_luma_samples and pic_height_in_luma_samples, I *think* this is more correct. This PR is for discussion. (See #345.) It makes the failures go away, but that does not mean it's correct :) The following poc will be stop failing if (only) this patch is applied: - poc2 #336 - CVE-2022-43238 - poc4 #338 - CVE-2022-43241 - poc6-1, poc6-2 #340 - CVE-2022-43242 - poc7-1, poc7-2 #341 - CVE-2022-43239 - poc8-1 #342 - CVE-2022-43244 - poc9-3 #343 - CVE-2022-43236 - poc10-2, poc10-3 #344 - CVE-2022-43237 - poc16 #350 - poc19 #353 The following are still failing if only this patch is applied, but they stop failing if #365 is applied as well, but will still fail with ONLY #365 applied (IOW, both are needed) - poc1 #335 - CVE-2022-43240 - poc3 #337 - CVE-2022-43235 - poc5 #339 - CVE-2022-43423 - poc9-1,poc9-2, poc9-4 #343 - CVE-2022-43236 - poc14 #348 - CVE-2022-43253 - poc15 #349 - CVE-2022-43248 - poc17-1, poc17-2 #351 - poc18 #352 - CVE-2022-43245 |

| recycle_sps_if_possible.patch | [PATCH] Don't update sps if they are only repeated This is an attempt to improve the mitigations from #365 and #366 and picks up an idea I described at #345: > One way would be just to look at the pointers of the SPS (fast and easy, but > may reject more than required), or investigate if the SPS used for the image > generations are "compatible". This changes do exactly this: It (very conservativly) checks if the old and new sps have identical information -- except the reference picture set, which I believe is supposed to be updated by new sps'). If they are basically identical, the old sps will be used instead of the new one, (of course, reference image set is updated from the new one) I'm using standalone operator== and helper functions to avoid changing ABI of the library; if an ABI bump would be done, of course this should go to the respective classes. |
