https://notcve.org/view.php?id=CVE-2018-18586
chmextract.c in the chmextract sample program, as distributed with libmspack before 0.8alpha, does not protect against absolute/relative pathnames in CHM files, leading to Directory Traversal. NOTE: the vendor disputes that this is a libmspack vulnerability, because chmextract.c was only intended as a source-code example, not a supported application ** EN DISPUTA ** chmextract.c en el programa de muestra chmextract, tal y como se distribuye en libmspack en versiones anteriores a la 0.8alpha, no protege contra nombres de ruta absoluta/relativa en archivos CHM, lo que conduce a un salto de directorio. NOTA: el fabricante discute que esto sea una vulnerabilidad en libmspack, ya que chmextract.c solo se diseñó como ejemplo de código abierto, no una aplicación soportada. • https://bugs.debian.org/911639 https://github.com/kyz/libmspack/commit/7cadd489698be117c47efcadd742651594429e6d https://security.gentoo.org/glsa/201903-20 https://www.openwall.com/lists/oss-security/2018/10/22/1 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

In mspack/cab.h in libmspack before 0.8alpha and cabextract before 1.8, the CAB block input buffer is one byte too small for the maximal Quantum block, leading to an out-of-bounds write. En mspack/cab.h en libmspack en versiones anteriores a la 0.8alpha y cabextract en versiones anteriores a la 1.8, el búfer de entrada de bloques CAB es un byte más pequeño para el bloque Quantum máximo, lo que conduce a una escritura fuera de límites. • https://access.redhat.com/errata/RHSA-2019:2049 https://bugs.debian.org/911640 https://github.com/kyz/libmspack/commit/40ef1b4093d77ad3a5cfcee1f5cb6108b3a3bcc2 https://lists.debian.org/debian-lts-announce/2018/10/msg00017.html https://security.gentoo.org/glsa/201903-20 https://usn.ubuntu.com/3814-1 https://usn.ubuntu.com/3814-2 https://usn.ubuntu.com/3814-3 https://www.cabextract.org.uk/#changes https://www.openwall.com/lists/oss-security/2018/10/22/1 https://www • CWE-787: Out-of-bounds Write •
