Background ========== gdb is the GNU project's debugger, facilitating the analysis and debugging of applications. The BFD library provides a uniform method of accessing a variety of object file formats. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-devel/gdb < 9.1 >= 9.1 Description =========== It was discovered that gdb didn't properly validate the ELF section sizes from input file. Impact ====== A remote attacker could entice a user to open a specially crafted ELF binary using gdb, possibly resulting in information disclosure or a Denial of Service condition.
