Alpine: squid: security update to 6.4-r0

medium Tenable Self-Hosted Container Security Plugin ID 408183

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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. (CVE-2023-46724)

- SQUID is vulnerable to HTTP request smuggling, caused by chunked decoder lenience, allows a remote
attacker to perform Request/Response smuggling past firewall and frontend security systems.
(CVE-2023-46846)

- Squid is vulnerable to a Denial of Service, where a remote attacker can perform buffer overflow attack by
writing up to 2 MB of arbitrary data to heap memory when Squid is configured to accept HTTP Digest
Authentication. (CVE-2023-46847)

- Squid is vulnerable to Denial of Service, where a remote attacker can perform DoS by sending ftp:// URLs
in HTTP Request messages or constructing ftp:// URLs from FTP Native input. (CVE-2023-46848)
