Due to improper input validation, it allows a trusted client to perform HTTP Request Smuggling and access services otherwise forbidden by the security controls. This occurs for certain uri_whitespace configuration settings. CVE-2020-25097 openSUSE Leap 15.2:squid-4.15-lp152.2.9.1 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://lists.opensuse.org/archives/list/security-announce@lists.opensuse.org/thread/E33JWP5CXQF3EVKKDRECX4457F2ILQP2/ https://www.suse.com/security/cve/CVE-2020-25097.html CVE-2020-25097 https://bugzilla.suse.com/1183436 SUSE Bug 1183436 An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a buffer-management bug, it allows a denial of service. When resolving a request with the urn: scheme, the parser leaks a small amount of memory. However, there is an unspecified attack methodology that can easily trigger a large amount of memory consumption.

Due to incorrect parser validation, it allows a Denial of Service attack against the Cache Manager API. This allows a trusted client to trigger memory leaks that. over time, lead to a Denial of Service via an unspecified short query string. This attack is limited to clients with Cache Manager API access privilege.
