What is CVE-2019-1010060?

The NASA CFITSIO software, prior to version 3.43, is susceptible to a buffer overflow, enabling potential arbitrary code execution by remote unauthenticated attackers. This vulnerability arises from the mishandling of long strings in over 40 source files, including issues within the ftp_status function in drvrnet.c, which can begin with specific characters like '4'. This vulnerability is distinct from previous issues documented in CVEs 2018-3846 to 2018-3849, emphasizing the need for prompt updates to mitigate risk.
