Description
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.
Affected configurations
• oniguruma project oniguruma (>= 6.0.0 < 6.9.4)
• oniguruma project oniguruma 6.9.4
• fedoraproject fedora 30
