Description

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.

Affected configurations

• oniguruma project oniguruma (>= 6.0.0 <= 6.9.3) • oniguruma project oniguruma 6.9.4 • debian debian linux 8.0 • fedoraproject fedora 30 • fedoraproject fedora 31 • redhat enterprise linux 8.0
