Alpine: cups: security update to 2.4.2-r2
high Tenable Cloud Security Plugin ID 403940
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- OpenPrinting CUPS is an open source printing system. In versions 2.4.2 and prior, a heap buffer overflow
vulnerability would allow a remote attacker to launch a denial of service (DoS) attack. A buffer overflow
vulnerability in the function `format_log_line` could allow remote attackers to cause a DoS on the
affected system. Exploitation of the vulnerability can be triggered when the configuration file
`cupsd.conf` sets the value of `loglevel `to `DEBUG`. No known patches or workarounds exist at time of
publication. (CVE-2023-32324)
- OpenPrinting CUPS is a standards-based, open source printing system for Linux and other Unix-like
operating systems. Starting in version 2.0.0 and prior to version 2.4.6, CUPS logs data of free memory to
the logging service AFTER the connection has been closed, when it should have logged the data right
before. This is a use-after-free bug that impacts the entire cupsd process. The exact cause of this issue
is the function `httpClose(con->http)` being called in `scheduler/client.c`. The problem is that httpClose
always, provided its argument is not null, frees the pointer at the end of the call, only for
cupsdLogClient to pass the pointer to httpGetHostname. This issue happens in function `cupsdAcceptClient`
if LogLevel is warn or higher and in two scenarios: there is a double-lookup for the IP Address
(HostNameLookups Double is set in `cupsd.conf`) which fails to resolve, or if CUPS is compiled with TCP
wrappers and the connection is refused by rules from `/etc/hosts.allow` and `/etc/hosts.deny`. Version
2.4.6 has a patch for this issue. (CVE-2023-34241)
