Instructions:

Identification

Identify if we have the software, in 16.09, 17.03, and unstable. Then determine if we are vulnerable, and make a comment with your findings. It can also be helpful to specify if you think there is a patch, or if it can be fixed via a general update.

Example:

unstable: we are not vulnerable (link to the package)
17.03: we are vulnerable (link to the package)
16.09: we don't have it packaged

IMPORTANT: If you believe there are possibly related issues, bring them up on the parent issue!

Patching

Start by commenting on this issue saying you're working on a patch. This way, we don't duplicate work.

If you open a pull request, tag this issue and the master issue for the roundup.

If you commit the patch directly to a branch, please leave a comment on this issue with the branch and the commit hash, example:

Description:
jasper is an open-source initiative to provide a free software-based reference 
implementation of the codec specified in the JPEG-2000 Part-1 standard.

Another round of fuzzing shows that a crafted image causes a read overflow.

The complete ASan output:

# imginfo -f $FILE
warning: ignoring unknown marker segment (0xff70)
type = 0xff70 (UNKNOWN); len = 35;00 01 43 72 65 61 74 6f 74 3a 30 4a 61 73 50

Working, updating to latest version

[ndowens]

Added some additional checking to prevent a potential integer overflow; Not sure if this is a commit to fix this issue; That msg came from a commit msg for this software

Edit: I dont think it does, but could be wrong

[7c6f434c]

Hm, the upstream issue is open. It also has a testcase, interesting.

[7c6f434c]

imginfo -f 00126-jasper-heapoverflow-jpc_dec_decodepkt gives imginfo: /tmp/nix-build-jasper-2.0.10.drv-0/jasper-2.0.10/src/libjasper/jpc/jpc_t2cod.c:305: jpc_pi_nextrpcl: Assertion `pi->prcno < pi->pirlvl->numprcs' failed.

Does the updated version do the same?

[7c6f434c]

… Yes it does.

If only we could snooze this issue until the upstream issue mdadams/jasper#114 gets closed or mentioned in PR/commit… (being able to translate comments from the upstream issue would also be nice)

[grahamc]

fwiw I've merged the .12 update, because they're usually worth updating to. This issue is still one.

The patches I madee are:
