DEBIAN-CVE-2019-12519 PUBLISHED CVSS 9.800000190734863 CRITICAL

Record from OSV · Published April 15, 2020

An issue was discovered in Squid through 4.7. When handling the tag esi:when when ESI is enabled, Squid calls ESIExpression::Evaluate. This function uses a fixed stack buffer to hold the expression while it's being evaluated. When processing the expression, it could either evaluate the top of the stack, or add a new member to the stack. When adding a new member, there is no check to ensure that the stack won't overflow.
