简介
CentOS Linux 主机缺少一个或多个安全更新。描述
如 TuxCare CENTOS7：CLSA-2025：1738672047公告所述，CentOS Linux 7 主机上存在安装的程序包，该漏洞会受到多个漏洞的影响。- 在 Linux 内核中发现一个归类为“危急”的漏洞。受此漏洞影响的是 Bluetooth 组件的 net/bluetooth/l2cap_core.c 文件的 l2cap_conn_del 函数。操纵此漏洞可导致释放后使用。建议应用补丁修复此问题。此漏洞的标识符为 VDB-211944。(CVE-2022-3640)
- 已修复 Linux 内核中的下列漏洞：ceph: prevent use-after-free in encode_cap_msg() In fs/ceph/caps.c, in encode_cap_msg(), use after free error was caught by KASAN at this line - 'ceph_buffer_get(arg->xattr_buf);'. This implies before the refcount could be increment here, it was freed. In same file, in handle_cap_grant() refcount is decremented by this line - 'ceph_buffer_put(ci->i_xattrs.blob);'. It appears that a race occurred and resource was freed by the latter line before the former line could increment it. encode_cap_msg() is called by __send_cap() and
__send_cap() is called by ceph_check_caps() after calling __prep_cap(). __prep_cap() is where arg->xattr_buf is assigned to ci->i_xattrs.blob. This is the spot where the refcount must be increased to prevent use after free error. (CVE-2024-26689)
- 已修复 Linux 内核中的下列漏洞：drm/amdgpu: add missing size check in amdgpu_debugfs_gprwave_read() Avoid a possible buffer overflow if size is larger than 4K. (cherry picked from commit f5d873f5825b40d886d03bd2aede91d4cf002434) (CVE-2024-50282)
- 已修复 Linux 内核中的下列漏洞：hv_sock: Initializing vsk->trans to NULL to prevent a dangling pointer When hvs is released, there is a possibility that vsk->trans may not be initialized to NULL, which could lead to a dangling pointer. This issue is resolved by initializing vsk->trans to NULL. (CVE-2024-53103)
- 已修复 Linux 内核中的下列漏洞：netfilter: ipset: add missing range check in bitmap_ip_uadt When tb[IPSET_ATTR_IP_TO] is not present but tb[IPSET_ATTR_CIDR] exists, the values of ip and ip_to are slightly swapped. Therefore, the range check for ip should be done later, but this part is missing and it seems that the vulnerability occurs. So we should add missing range checks and remove unnecessary range checks. (CVE-2024-53141)
请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。
