Description Dhananjay Arunesh 2019-08-01 08:37:24 UTC

An Integer overflow in the getElfSections function in p_vmlinx.cpp in UPX 3.95 allows remote attackers to cause a denial of service (crash) via a skewed offset larger than the size of the PE section in a UPX packed executable, which triggers an allocation of excessive memory.
