Several security vulnerabilities have been discovered in Squid, a full featured
web proxy cache. Due to programming errors in Squid’s HTTP request parsing,
remote attackers may be able to execute a denial of service attack by sending
large X-Forwarded-For header or trigger a stack buffer overflow while
performing HTTP Digest authentication. Other issues facilitate request
smuggling past a firewall or a denial of service against Squid’s Helper process
management.
In regard to CVE-2023-46728: Please note that support for the Gopher protocol
has simply been removed in future Squid versions. There are no plans by the
upstream developers of Squid to fix this issue.
It was discovered that mqtt-client incorrectly handled memory while parsing
malformed MQTT frames. An attacker could possibly use this issue to cause a
crash, resulting in a denial of service, or possibly execute arbitrary code.
It was discovered that ncurses incorrectly handled certain function return
values, possibly leading to segmentation fault. A local attacker could possibly
use this to cause a denial of service (system crash).
It was discovered that HtmlCleaner incorrectly handled certain html
documents. An attacker could possibly use this issue to cause a denial
of service via application crash.
