Package        : libraw
Version        : 0.19.2-2+deb10u2
CVE ID         : CVE-2020-15503

This update adds size checks to thumbnail extraction. Prior to these checks, it
was possible to overflow arguments to e.g. malloc and thus cause out-of-bounds
memory accesses.

For Debian 10 buster, this problem has been fixed in version
0.19.2-2+deb10u2.

We recommend that you upgrade your libraw packages.

its security tracker page at:
