Severity: Normal Title: Binutils: Multiple vulnerabilities Date: July 10, 2021 Bugs: #678806, #761957, #764170 ID: 202107-24
Synopsis
Multiple vulnerabilities have been found in Binutils, the worst of which could result in a Denial of Service condition.
Background
The GNU Binutils are a collection of tools to create, modify and analyse binary files. Many of the files use BFD, the Binary File Descriptor library, to do low-level manipulation.
Affected packages
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-devel/binutils < 2.35.2 >= 2.35.2
Description
Multiple vulnerabilities have been discovered in Binutils. Please review the CVE identifiers referenced below for details.
Impact
Please review the referenced CVE identifiers for details.
Workaround
There is no known workaround at this time.
