A size-validation issue was discovered in opj_j2k_write_sot in lib/openjp2/j2k.c in OpenJPEG 2.2.0. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service (heap-based buffer overflow affecting opj_write_bytes_LE in lib/openjp2/cio.c) or possibly remote code execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-14152. Existe un error de validación de tamaño en opj_j2k_write_sot en lib/openjp2/j2k.c en OpenJPEG 2.2.0. La vulnerabilidad da lugar a una escritura fuera de límites que puede causar una denegación de servicio remota (desbordamiento de búfer basado en montículos que afecta a opj_write_bytes_LE en lib/openjp2/cio.c) o una posible ejecución remota de código. • http://www.securityfocus.com/bid/100677 https://blogs.gentoo.org/ago/2017/09/06/heap-based-buffer-overflow-in-opj_write_bytes_le-cio-c-incomplete-fix-for-cve-2017-14152 https://github.com/uclouvain/openjpeg/commit/dcac91b8c72f743bda7dbfa9032356bc8110098a https://github.com/uclouvain/openjpeg/issues/991 https://security.gentoo.org/glsa/201710-26 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
