CVE-2026-42046
HighSummary
In the libcaca library version 0.99.beta20 and earlier, there is an integer overflow vulnerability in the canvas import functionality, allowing an attacker to cause a controlled heap out-of-bounds write. This may lead to memory corruption or remote code execution.
Risk Assessment
This vulnerability poses a serious risk to organizations as it may lead to remote code execution, threatening the integrity and confidentiality of systems.
Recommendation
It is recommended to update the libcaca library to a version that includes the fix to eliminate this vulnerability.

Original NVD description (English source)
libcaca is a colour ASCII art library. In 0.99.beta20 and earlier, an integer overflow vulnerability in libcaca'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 "caca" 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. Commit fb77acff9ba6bb01d53940da34fb10f20b156a23 fixes this vulnerability.
