USN-6737-1: GNU C Library vulnerability
18 April 2024
GNU C Library could be made to crash or run programs if it processed specially crafted data.
Releases
Packages
- glibc - GNU C Library
Details
Charles Fol discovered that the GNU C Library iconv feature incorrectly
handled certain input sequences. An attacker could use this issue to cause
the GNU C Library 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 23.10
Ubuntu 22.04
Ubuntu 20.04
After a standard system update you need to reboot your computer to make
all the necessary changes.
