CVE-2020-8517

Priority
Description
An issue was discovered in Squid before 4.10. Due to incorrect input
validation, the NTLM authentication credentials parser in ext_lm_group_acl
may write to memory outside the credentials buffer. On systems with memory
access protections, this can result in the helper process being terminated
unexpectedly. This leads to the Squid process also terminating and a denial
of service for all clients using the proxy.
