Detail

Synopsis

A buffer overflow in gdb might allow a remote attacker to cause a Denial of Service condition.

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.

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.

Workaround

There is no known workaround at this time.

Resolution

All gdb users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-devel/gdb-9.1"
