| Vetor | AV:N/AC:M/Au:N/C:C/I:N/A:C |
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.Exploit
