Vulnerability Name:

CVE-2019-19012 (CCN-172008)

Assigned:2019-11-08
Published:2019-11-08
Updated:2020-08-24
Summary: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.
