CVE-2019-19203 low priority: Debian including 1 source packages (libonig), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
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.
