CVE-2018-20376 describes an out-of-bounds write vulnerability in Tiny C Compiler (TCC) version 0.9.27, specifically within the asm_parse_directive function in tccasm.c. This medium-severity vulnerability (CVSS 5.5) can be triggered by compiling a specially crafted source file, leading to an 8-byte out-of-bounds write that could result in a denial of service. While the attack requires user interaction (UI:R) and local access (AV:L), there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
