Detailsinfo

A vulnerability has been found in GNU binutils 2.29 (Programming Tool Software) and classified as critical. Affected by this vulnerability is the function read_section of the file dwarf2.c of the component libbfd. The manipulation as part of a ELF File leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The read_section function in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, allows remote attackers to cause a denial of service (parse_comp_unit heap-based buffer over-read and application crash) via a crafted ELF file.

The bug was discovered 09/04/2017. The weakness was published 09/04/2017 as Bug 22047 as not defined bug report (Bugzilla). The advisory is shared at sourceware.org.
