In radare 2.0.1, a memory corruption vulnerability exists in store_versioninfo_gnu_verdef() and store_versioninfo_gnu_verneed() in libr/bin/format/elf/elf.c, as demonstrated by an invalid free. This error is due to improper sh_size validation when allocating memory.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
