Libcaca · Libcaca · CVE-2018-20547
**Name of the Vulnerable Software and Affected Versions**
libcaca version 0.99.beta19
**Description**
The issue is related to an integer overflow in the `get rgba default` function, located in caca/dither.c, which can lead to an illegal READ memory access, particularly for 24bpp data. This can potentially allow a remote attacker to gain unauthorized access to protected information.
**Recommendations**
For libcaca version 0.99.beta19, consider disabling the `get rgba default` function as a temporary workaround until a patch is available. Restrict access to the caca/dither.c module to minimize the risk of exploitation. Avoid using the affected function for 24bpp data until the issue is resolved.
