    Package        : squid3
    Version        : 3.4.8-6+deb8u8
    CVE ID         : CVE-2019-12525 CVE-2019-12529
    
    
    Squid, a high-performance proxy caching server for web clients, has been
    found vulnerable to denial of service attacks associated with HTTP
    authentication header processing.
    
    CVE-2019-12525
    
        Due to incorrect buffer management Squid is vulnerable to a denial
        of service attack when processing HTTP Digest Authentication
        credentials.
    
        Due to incorrect input validation the HTTP Request header parser for
        Digest authentication may access memory outside the allocated memory
        buffer.
    
        On systems with memory access protections this can result in the
        Squid process being terminated unexpectedly. Resulting in a denial
        of service for all clients using the proxy.
    
    CVE-2019-12529
    
        Due to incorrect buffer management Squid is vulnerable to a denial
        of service attack when processing HTTP Basic Authentication
        credentials.
    
        Due to incorrect string termination the Basic authentication
        credentials decoder may access memory outside the decode buffer.
    
        On systems with memory access protections this can result in the
        Squid process being terminated unexpectedly. Resulting in a denial
        of service for all clients using the proxy.
    
    For Debian 8 "Jessie", these problems have been fixed in version
    3.4.8-6+deb8u8.
    
    We recommend that you upgrade your squid3 packages.
