CVE-2018-7186 describes a critical stack-based buffer overflow vulnerability in Leptonica versions prior to 1.75.3, affecting Debian Linux and Leptonica itself. This flaw allows remote attackers to cause a denial of service or potentially achieve other unspecified impacts by providing a long string to functions like gplotRead and ptaReadStream, which do not properly limit the length of %s format arguments in fscanf or sscanf. With a CVSS score of 9.8 (CRITICAL), it presents a severe risk due to its network-based attack vector, low complexity, and high impact on confidentiality, integrity, and availability. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
