Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
+++ This bug was initially created as a clone of Bug #2072469 +++
In jwe.c, on line 1952:
cek = cjose_get_alloc()(cek_len);
memcpy(cek, jwe->cek, cek_len);
allocation result is not checked. We should add (before memcpy):
if (!cek) {
CJOSE_ERROR(err, CJOSE_ERR_NO_MEMORY);
return NULL;
}
Bug registered at https://github.com/cisco/cjose/issues/110.
Cisco does not maintain this repo anymore; do you plan to maintain the package in Redhat?
For info, there's a fork trying to keep this software up-to-date (and it includes this patch): https://github.com/zmartzone/cjose/tree/version-0.6.2.x

Hi Tomas,
Are you still working on this? If yes, can we plan the DTM/ITM/ITR? If not, can you please move it back to NEW, so we can make sure the status is not misleading? let me know if I can help somehow :)

This is an easy update and the fix is available upstream. We are limited by QE capacity here - I think it is good candidate for Q1.
We do not have any real problem reported by customers but such things may cause security issues, so we should fix it soon.

I'd also like to ask you to switch to the maintenance fork at https://github.com/zmartzone/cjose, as suggested before in https://github.com/cisco/cjose/issues/121 ; the parent project's last commit was 3.5 years ago, and issues no longer get addressed; for the record, Debian has made that switch https://salsa.debian.org/debian/cjose

Sure Hans, I count on that.

I switched to the maintenance fork, thanks for maintaining it
