Package : libcaca Version : 0.99.beta19-2.2+deb11u1 CVE ID : CVE-2021-30498 CVE-2021-30499

Two issues have been found in libcaca, a colour ASCII art library.
Both are related to heap buffer overflow, which might lead to memory corruption.

For Debian 11 bullseye, these problems have been fixed in version 0.99.beta19-2.2+deb11u1.

We recommend that you upgrade your libcaca packages.
