Package : gerbv
Version : 2.7.0-1+deb10u2
CVE IDs : CVE-2021-40401 CVE-2021-40403

Two vulnerabilities were discovered gerbv, a Gerber file viewer. Most
Printed Circuit Board (PCB) design programs can export data to a
Gerber file.

* CVE-2021-40401: A use-after-free vulnerability existed in the
RS-274X aperture definition tokenization functionality. A
specially-crafted gerber file could have led to code execution.

* CVE-2021-40403: An information disclosure vulnerability existed in
the pick-and-place rotation parsing functionality. A
specially-crafted pick-and-place file could have exploited the
missing initialization of a structure in order to leak memory
contents.

For Debian 10 buster, these problems have been fixed in version
2.7.0-1+deb10u2.

We recommend that you upgrade your gerbv packages.
