Name of the Vulnerable Software and Affected Versions USC iLab cereal versions 1.3.0 and earlier

Description An issue was discovered in the serialization of an initialized C/C++ long double variable into a BinaryArchive or PortableBinaryArchive, which leaks several bytes of stack or heap memory. This can reveal sensitive information, such as memory layout or private keys, if the archive is distributed outside of a trusted context.

Recommendations For versions 1.3.0 and earlier, consider restricting the distribution of archives to trusted contexts to minimize the risk of exploitation. As a temporary workaround, avoid serializing initialized C/C++ long double variables into BinaryArchive or PortableBinaryArchive until a patch is available.
