    Software Description:

    It was discovered that Squid incorrectly handled certain SNMP packets. A

    cross-site scripting (XSS) attacks. (CVE-2019-13345)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 19.04:
      squid                           4.4-1ubuntu2.1
    
    Ubuntu 18.04 LTS:
      squid3                          3.5.27-1ubuntu1.2
