Name of the Vulnerable Software and Affected Versions
libmspack versions prior to 0.7alpha
Description
The issue is related to the
kwajd read headers function in libmspack, which can cause a one or two byte overwrite due to bad KWAJ file header extensions. This can lead to a buffer overflow in memory. The exploitation of this issue may allow a remote attacker to cause a denial of service using a KWAJ file.Recommendations
For versions prior to 0.7alpha, update to version 0.7alpha or later to resolve the issue. As a temporary workaround, consider restricting the use of the
kwajd read headers function until a patch is available. Avoid using the kwajd read headers function with untrusted KWAJ files to minimize the risk of exploitation.Fix
