CVE-2020-23026

Published: 3 January 2022

A NULL pointer dereference in the main() function dhry_1.c of dhrystone 2.1 causes a denial of service (DoS).

Notes

AuthorNote
sbeattie
gcc-3.3 only provides libstdc++5
alexmurray
u-boot and gcc both contain embedded copies of dhrystone
rodrigo-zaiden
u-boot is not building with dhrystone in Ubuntu.
gcc includes dhrystone in the testsuite, so there is no
impact in the usability of gcc and can be ignored.
