Hi Vijay, This fix is already submitted to OE-core community and added in queue for dunfell branch. Please check the status of community patches here: https://patchwork.yoctoproject.org/project/oe-core/list/ Thanks, Sanjay -----Original Message----- From: openembedded-core@lists.openembedded.org <openembedded-core@lists.openembedded.org> On Behalf Of Vijay Anusuri Sent: Wednesday, June 14, 2023 12:24 PM To: openembedded-core@lists.openembedded.org Cc: Vijay Anusuri <vanusuri@mvista.com> Subject: [OE-core][dunfell][PATCH] cups: Fix CVE-2023-32324 From: Vijay Anusuri <vanusuri@mvista.com> OpenPrinting CUPS is an open source printing system. In versions 2.4.2 and prior, a heap buffer overflow vulnerability would allow a remote attacker to launch a denial of service (DoS) attack. A buffer overflow vulnerability in the function `format_log_line` could allow remote attackers to cause a DoS on the affected system. Exploitation of the vulnerability can be triggered when the configuration file `cupsd.conf` sets the value of `loglevel `to `DEBUG`. No known patches or workarounds exist at time of publication.
