USN-6737-1: GNU C Library vulnerability

Releases

• Ubuntu 23.10
• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS

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

• libc6 - 2.38-1ubuntu6.2

Ubuntu 22.04

• libc6 - 2.35-0ubuntu3.7

Ubuntu 20.04

• libc6 - 2.31-0ubuntu9.15

After a standard system update you need to reboot your computer to make
all the necessary changes.
