NVD Description
Note: Versions mentioned in the description apply only to the upstream php-pecl-xdebug-debugsource package and not the php-pecl-xdebug-debugsource package as distributed by Centos.
An issue was discovered in Oniguruma 6.x before 6.9.4_rc2. In the function gb18030_mbc_enc_len in file gb18030.c, a UChar pointer is dereferenced without checking if it passed the end of the matched string. This leads to a heap-based buffer over-read.
