NVD Description
Note: Versions mentioned in the description apply only to the upstream rubygem-psych package and not the rubygem-psych package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
An integer overflow in the search_in_range function in regexec.c in Oniguruma 6.x before 6.9.4_rc2 leads to an out-of-bounds read, in which the offset of this read is under the control of an attacker. (This only affects the 32-bit compiled version). Remote attackers can cause a denial-of-service or information disclosure, or possibly have unspecified other impact, via a crafted regular expression.
