USN-4326-1: libiberty vulnerabilities
8 April 2020
Several security issues were fixed in libiberty.
Releases
Packages
- libiberty - library of utility functions used by GNU programs
Details
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
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.04
Ubuntu 16.04
In general, a standard system update will make all the necessary changes.
