cabextract before 1.6 does not properly check for leading slashes when extracting files, which allows remote attackers to conduct absolute directory traversal attacks via a malformed UTF-8 character that is changed to a UTF-8 encoded slash.

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.

An integer wrap-around flaw has been reported in the way cabextract processed certain Cabinet (.cab) archive files. If a local user was tricked into opening a specially-crafted .cab archive in test archive mode, it could lead to cabextract executable crash.

A deficiency has been reported in the way cabextract extracted certain Cabinet (.cab) files, using the MZ-ZIP and Quantum decompressors. If a local user was tricked into opening a specially-crafted .cab file, it could lead to infinite loop.
