21 Nov 2019 — 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. Se detectó un problema en Oniguruma versiones 6.x anteriores a 6.9.4_rc2. En la función gb18030_mbc_enc_len en el archivo gb18030.c, un puntero UChar es desreferenciado sin comprobar si pasó el final de la cadena coincidente. • https://github.com/ManhNDd/CVE-2019-19203 • CWE-125: Out-of-bounds Read •

16 Nov 2019 — An integer overflow in the search_in_range function in regexec.c in Oniguruma 6.x before 6.9.4_rc2 leads to an out-of-bounds read, in which the offset of this read is under the control of an attacker. (This only affects the 32-bit compiled version). Remote attackers can cause a denial-of-service or information disclosure, or possibly have unspecified other impact, via a crafted regular expression.
