CVE-2019-12495 not yet assigned priority: Debian including 1 source packages (tcc), 4 status rows across 4 suites (bookworm, bullseye, sid, trixie): resolved 4.
An issue was discovered in Tiny C Compiler (aka TinyCC or TCC) 0.9.27. Compiling a crafted source file leads to a one-byte out-of-bounds write in the gsym_addr function in x86_64-gen.c. This occurs because tccasm.c mishandles section switches.
