简介
远程 Red Hat 主机缺少一个或多个安全更新。描述
远程 Redhat Enterprise Linux 8 主机上安装的多个程序包受到 RHSA-2022: 1759 公告。- QEMU：block：fdc：空指针取消引用可能导致客户机崩溃 (CVE-2021-20196)
- ntfs-3g：ntfs_get_attribute_value() 中存在越界堆缓冲区访问，这是未正确检查 MFT 记录中的 bytes_in_use 值所致 (CVE-2021-33285)
- ntfs-3g：通过特别构建的 Unicode 字符串可触发堆缓冲区溢出 (CVE-2021-33286)
- ntfs-3g：ntfs_attr_pread_i() 中存在堆缓冲区溢出，通过特别构建的 NTFS 属性，可触发此问题 (CVE-2021-33287)
- ntfs-3g：通过特别构建的 MFT 区段可触发堆缓冲区溢出 (CVE-2021-33289)
- ntfs-3g：通过特别构建的 NTFS inode 路径名称可触发堆缓冲区溢出 (CVE-2021-35266)
- ntfs-3g：在修正 MFT 和 MFTMirror 区段之间的差异时，可触发堆栈缓冲区溢出 (CVE-2021-35267)
- ntfs-3g：ntfs_inode_real_open() 中存在堆缓冲区溢出，通过特别构建的 NTFS inode 可触发此问题 (CVE-2021-35268)
- ntfs-3g：ntfs_attr_setup_flag() 中存在堆缓冲区溢出，通过 MFT 中特别构建的 NTFS 属性，可触发此问题 (CVE-2021-35269)
- hivex：由于递归调用 _get_children() 导致堆栈溢出 (CVE-2021-3622)
- nbdkit：STARTTLS 上的 NBD_OPT_STRUCTURED_REPLY 注入漏洞 (CVE-2021-3716)
- QEMU：virtio-net：virtio_net_receive_rcu 中存在堆释放后使用漏洞 (CVE-2021-3748)

- ntfs-3g：ntfs_attr_find_in_attrdef() 中存在越界读取，通过无效属性可触发此问题 (CVE-2021-39255)
- ntfs-3g：ntfs_inode_lookup_by_name() 中存在堆缓冲区溢出 (CVE-2021-39256)
- ntfs-3g：ntfs_attr_pwrite() 中存在无限递归，通过未分配的位图可触发此问题 (CVE-2021-39257)
- ntfs-3g：ntfs_attr_find() 和 ntfs_external_attr_find() 中存在越界读取 (CVE-2021-39258)
- ntfs-3g：ntfs_inode_lookup_by_name() 中存在越界访问，这是未经审查的属性长度所致 (CVE-2021-39259)
- ntfs-3g：ntfs_inode_sync_standard_information() 中存在越界访问 (CVE-2021-39260)
- ntfs-3g：ntfs_compressed_pwrite() 中存在堆缓冲区溢出 (CVE-2021-39261)
- ntfs-3g：ntfs_decompress() 中存在越界访问 (CVE-2021-39262)
- ntfs-3g：ntfs_get_attribute_value() 中存在堆缓冲区溢出，这是未经审查的属性所致 (CVE-2021-39263)
- libvirt：VM 关闭期间的分段错误可导致 vdsm 挂起 (CVE-2021-3975)
- QEMU：在 block/mirror.c 的 mirror_wait_on_conflicts() 中发生空指针取消引用 (CVE-2021-4145)
