CVE-2003-0826 describes a heap-based buffer overflow vulnerability in the lsh daemon (lshd) of GNU lsh. This flaw, stemming from improper handling of long input in several functions, allows remote attackers to execute arbitrary code. With a CVSS score of 7.5, it represents a high-severity risk, requiring no authentication and having a low attack complexity, potentially leading to partial confidentiality, integrity, and availability compromise. While not listed in CISA KEV or Hot List, and lacking Metasploit/Nuclei modules, two ExploitDB entries confirm the existence of exploit code, despite minimal community discussion or media coverage.
