Ubuntu 16.04 LTS / 18.04 LTS : libiberty vulnerabilities (USN-4326-1)

high Nessus Plugin ID 135398


The remote Ubuntu host is missing a security-related patch.


It was discovered that libiberty incorrectly handled parsing certain binaries. If a user or automated system were tricked into processing a specially crafted binary, a remote attacker could use this issue to cause libiberty to crash, resulting in a denial of service, or possibly execute arbitrary code.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libiberty-dev package.
