Description

On Juniper Networks SRX Series with ICAP (Internet Content Adaptation Protocol) redirect service enabled, a double free vulnerability can lead to a Denial of Service (DoS) or Remote Code Execution (RCE) due to processing of a specific HTTP message. Continued processing of this specific HTTP message may result in an extended Denial of Service (DoS). The offending HTTP message that causes this issue may originate both from the HTTP server or the client. This issue affects Juniper Networks Junos OS on SRX Series: 18.1 versions prior to 18.1R3-S9; 18.2 versions prior to 18.2R3-S3; 18.3 versions prior to 18.3R2-S4, 18.3R3-S1; 18.4 versions prior to 18.4R2-S5, 18.4R3; 19.1 versions prior to 19.1R2; 19.2 versions prior to 19.2R1-S2, 19.2R2; 19.3 versions prior to 19.3R2.
