CVE-2023-34241 (CNNVD-202306-1640)
中文标题:
OpenPrinting CUPS 资源管理错误漏洞
英文标题:
CUPS vulnerable to use-after-free in cupsdAcceptClient()
漏洞描述
中文描述:
OpenPrinting CUPS是OpenPrinting公司的一个适用于 Linux® 和其他类 Unix® 操作系统的基于标准的开源打印系统。 OpenPrinting CUPS 2.2.0到2.4.6版本存在资源管理错误漏洞,该漏洞源于在scheduler/client.c中调用了httpClose(con->http)函数,httpClose 总是在其参数不为 null 的情况下在调用结束时释放指针,仅让 cupsdLogClient 将指针传递给 httpGetHostname。
英文描述:
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.
