Description

In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. An integer overflow was found in expat. The issue occurs in storeRawNames() by abusing the m_buffer expansion logic to allow allocations very close to INT_MAX and out-of-bounds heap writes. This flaw can cause a denial of service or potentially arbitrary code execution.
