{"id":"USN-4356-1","summary":"squid, squid3 vulnerabilities","details":"Jeriko One discovered that Squid incorrectly handled certain Edge Side\nIncludes (ESI) responses. A malicious remote server could cause Squid to\ncrash, possibly poison the cache, or possibly execute arbitrary code.\n(CVE-2019-12519, CVE-2019-12521)\n\nIt was discovered that Squid incorrectly handled the hostname parameter to\ncachemgr.cgi when certain browsers are used. A remote attacker could\npossibly use this issue to inject HTML or invalid characters in the\nhostname parameter. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04\nLTS, and Ubuntu 19.10. (CVE-2019-18860)\n\nClément Berthaux and Florian Guilbert discovered that Squid incorrectly\nhandled Digest Authentication nonce values.
