Description SMASH SMASH 2023-11-02 04:34:01 UTC
Squid is a caching proxy for the Web. Due to an Improper Validation of
Specified Index bug, Squid versions 3.3.0.1 through 5.9 and 6.0 prior to 6.4
compiled using `--with-openssl` are vulnerable to a Denial of Service attack
against SSL Certificate validation. This problem allows a remote server to
perform Denial of Service against Squid Proxy by initiating a TLS Handshake with
a specially crafted SSL Certificate in a server certificate chain. This attack
is limited to HTTPS and SSL-Bump. This bug is fixed in Squid version 6.4. In
addition, patches addressing this problem for the stable releases can be found
in Squid's patch archives. Those who you use a prepackaged version of Squid
should refer to the package vendor for availability information on updated
packages.
