Fixed In Version: binutils-2.29.1-25.fc28
Doc Type: Bug Fix
Doc Text:
Cause: The BFD library assumed that notes in ELF format files were well formed. Consequence: A specially crafted ELF file containing corrupt notes could trick the BFD library into allocating a negative amount of memory, thus triggering a memory exhaustion failure. Fix: Teach the BFD library to detect and report this kind of corrupt ELF file. Result: No more memory exhaustions when parsing this sort of corrupt file.
