Nutanix AOS : Multiple Vulnerabilities (NXSA-AOS-6.5.6)
critical Nessus Plugin ID 201039
Language:
Synopsis
The Nutanix AOS host is affected by multiple vulnerabilities .Description
The version of AOS installed on the remote host is prior to 6.5.6. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.5.6 advisory.- There are use-after-free vulnerabilities in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_connect and l2cap_le_connect_req functions which may allow code execution and leaking kernel memory (respectively) remotely via Bluetooth. A remote attacker could execute code leaking kernel memory via Bluetooth if within proximity of the victim. We recommend upgrading past commit https://www.google.com/url https://github.com/torvalds/linux/commit/711f8c3fb3db61897080468586b970c87c61d9e4 https://www.google.com/url (CVE-2022-42896)
- An issue was discovered in set_con2fb_map in drivers/video/fbdev/core/fbcon.c in the Linux kernel before 6.2.12. Because an assignment occurs only for the first vc, the fbcon_registered_fb and fbcon_display arrays can be desynchronized in fbcon_mode_deleted (the con2fb_map points at the old fb_info).
(CVE-2023-38409)
- An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel before 6.5.3. A buffer size may not be adequate for frames larger than the MTU. (CVE-2023-45871)
- A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. When the plug qdisc is used as a class of the qfq qdisc, sending network packets triggers use-after-free in qfq_dequeue() due to the incorrect .peek handler of sch_plug and lack of error checking in agg_dequeue(). We recommend upgrading past commit 8fc134fee27f2263988ae38920bc03da416b03d8. (CVE-2023-4921)
- A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660. (CVE-2024-1086)
- In the Linux kernel, the following vulnerability has been resolved: sched/membarrier: reduce the ability to hammer on sys_membarrier On some systems, sys_membarrier can be very expensive, causing overall slowdowns for everything. So put a lock on the path in order to serialize the accesses to prevent the ability for this to be called at too high of a frequency and saturate the machine. (CVE-2024-26602)
- This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due to this bug, the local variable that means let the host resolve the name could get the wrong value during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target buffer instead of copying just the resolved address there. The target buffer being a heap based buffer, and the host name coming from the URL that curl has been told to operate with. (CVE-2023-38545)
- CVE-2023-38545 is a heap-based buffer overflow vulnerability in the SOCKS5 proxy handshake in libcurl and curl. When curl is given a hostname to pass along to a SOCKS5 proxy that is greater than 255 bytes in length, it will switch to local name resolution in order to resolve the address before passing it on to the SOCKS5 proxy. However, due to a bug introduced in 2020, this local name resolution could fail due to a slow SOCKS5 handshake, causing curl to pass on the hostname greater than 255 bytes in length into the target buffer, leading to a heap overflow. The advisory for CVE-2023-38545 gives an example exploitation scenario of a malicious HTTPS server redirecting to a specially crafted URL. While it might seem that an attacker would need to influence the slowness of the SOCKS5 handshake, the advisory states that server latency is likely slow enough to trigger this bug. (CVE-2023-38545)
- This flaw allows an attacker to insert cookies at will into a running program using libcurl, if the specific series of conditions are met. libcurl performs transfers. In its API, an application creates easy handles that are the individual handles for single transfers. libcurl provides a function call that duplicates en easy handle called [curl_easy_duphandle](https://curl.se/libcurl/c/curl_easy_duphandle.html). If a transfer has cookies enabled when the handle is duplicated, the cookie-enable state is also cloned - but without cloning the actual cookies. If the source handle did not read any cookies from a specific file on disk, the cloned version of the handle would instead store the file name as `none` (using the four ASCII letters, no quotes). Subsequent use of the cloned handle that does not explicitly set a source to load cookies from would then inadvertently load cookies from a file named `none` - if such a file exists and is readable in the current directory of the program using libcurl. And if using the correct file format of course.
(CVE-2023-38546)
- CVE-2023-38546 is a cookie injection vulnerability in the curl_easy_duphandle(), a function in libcurl that duplicates easy handles. When duplicating an easy handle, if cookies are enabled, the duplicated easy handle will not duplicate the cookies themselves, but would instead set the filename to none.' Therefore, when the duplicated easy handle is subsequently used, if a source was not set for the cookies, libcurl would attempt to load them from the file named none' on the disk. This vulnerability is rated low, as the various conditions required for exploitation are unlikely. (CVE-2023-38546)
