CVE-2020-24240 |
GNU Bison before 3.7.1 has a use-after-free in _obstack_free in lib/obstack.c (called from gram_lex) when a '\0' byte is encountered. NOTE: there is a risk only if Bison is used with untrusted input, and the observed bug happens to cause unsafe behavior with a specific compiler/architecture. The bug report was intended to show that a crash may occur in Bison itself, not that a crash may occur in code that is generated by Bison. Published: August 25, 2020; 10:15:16 AM -0400 |
V4.0:(not available) V3.1: 5.5 MEDIUM V2.0: 7.1 HIGH |
