Name of the Vulnerable Software and Affected Versions
Oniguruma versions 6.x through 6.9.4 rc2
Description
The issue is related to an integer overflow in the
search in range function, which can lead to an out-of-bounds read. The offset of this read is under the control of an attacker, allowing remote attackers to cause a denial-of-service or information disclosure. This could potentially have other unspecified impacts. The vulnerability is specific to the 32-bit compiled version of the software.Recommendations
For Oniguruma versions 6.x through 6.9.4 rc2, update to version 6.9.4 rc2 or later to resolve the issue. As a temporary workaround, consider restricting the use of crafted regular expressions to minimize the risk of exploitation.
