CVE-2020-24240 (GCVE-0-2020-24240)
Vulnerability from cvelistv5 – Published: 2020-08-25 13:45 – Updated: 2024-08-04 15:12
VLAI
Summary
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.
Severity
No CVSS data available.

Summary
GNU Bison before 3.5.4 allows attackers to cause a denial of service (application crash). NOTE: there is a risk only if Bison is used with untrusted input, and an observed bug happens to cause unsafe behavior with a specific compiler/architecture. The bug reports were intended to show that a crash may occur in Bison itself, not that a crash may occur in code that is generated by Bison.

CVE-2020-14150 (GCVE-0-2020-14150)
Vulnerability from nvd – Published: 2020-06-15 16:52 – Updated: 2024-08-04 12:39
VLAI
Summary
GNU Bison before 3.5.4 allows attackers to cause a denial of service (application crash). NOTE: there is a risk only if Bison is used with untrusted input, and an observed bug happens to cause unsafe behavior with a specific compiler/architecture. The bug reports were intended to show that a crash may occur in Bison itself, not that a crash may occur in code that is generated by Bison.
Severity
No CVSS data available.
CWE
