CVE-2019-13224

Description

A use-after-free in onig_new_deluxe() in regext.c in Oniguruma 6.9.2 allows attackers to potentially cause information disclosure, denial of service, or possibly code execution by providing a crafted regular expression. The attacker provides a pair of a regex pattern and a string, with a multi-byte encoding that gets handled by onig_new_deluxe(). Oniguruma issues often affect Ruby, as well as common optional libraries for PHP and Rust. #### Bugs * <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=931878> #### Notes Author| Note ---|--- [ebarretto](<https://launchpad.net/~ebarretto>) | libevhtp doesn't ship oniguruma regex library since 1.2.15-1 [mdeslaur](<https://launchpad.net/~mdeslaur>) | doesn't look like php uses the vulnerable function
