Detailsinfo

A vulnerability, which was classified as critical, was found in GNU binutils 2.28 (Programming Tool Software). This affects the function pe_ILF_object_p of the component BFD Library. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The pe_ILF_object_p function in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, is vulnerable to a heap-based buffer over-read of size 4049 because it uses the strlen function instead of strnlen, leading to program crashes in several utilities such as addr2line, size, and strings. It could lead to information disclosure as well.

The bug was discovered 03/22/2017. The weakness was presented 03/22/2017 as Bug 20905 as not defined bug report (Bugzilla). The advisory is shared at sourceware.org.
