Name of the Vulnerable Software and Affected Versions
Oniguruma versions 6.2.0
Description
The issue is caused by an incorrect state transition in the
parse char class() function, leading to the possibility of using an uninitialized variable when writing to a buffer. This can result in a heap out-of-bounds write in the bitset set range() function during regular expression compilation, causing memory corruption. The estimated number of potentially affected devices worldwide is not specified. There is no information about real-world incidents where this issue was exploited.Recommendations
For Oniguruma version 6.2.0, consider updating to a newer version that contains a fix for this issue, as the current version is affected by the incorrect state transition in
parse char class() and the subsequent out-of-bounds write in bitset set range().
At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
