EulerOS 2.0 SP9 : bison (EulerOS-SA-2023-2604)

medium Nessus Plugin ID 179537


The remote EulerOS host is missing a security update.


According to the versions of the bison packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected bison packages.
