In 0.99.beta20 and earlier, an integer overflow vulnerability in libcaca&#8217;s canvas import functionality allows an attacker to cause a controlled heap out-of-bounds write (heap overflow) by supplying a crafted file in the &#8220;caca&#8221; format. Depending on the build configuration and memory allocator, this may lead to memory corruption or remote code execution. This is the same vulnerability as CVE-2021-3410 but the fix at that time was not fully correct.
