Summary:

Several security issues were fixed in ICU.

Software Description:
– icu: International Components for Unicode library

Details:

It was discovered that ICU incorrectly handled certain memory operations
when processing data. If an application using ICU processed crafted data,
a remote attacker could possibly cause it to crash or potentially execute
arbitrary code with the privileges of the user invoking the program.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:
