CVE-2018-6554
A memory leak in the irda_bind function in the irda subsystem was discovered. A local user can take advantage of this flaw to cause a denial of service (memory consumption).
CVE-2018-6555
A flaw was discovered in the irda_setsockopt function in the irda subsystem, allowing a local user to cause a denial of service (use-after-free and system crash).
CVE-2018-7755
Brian Belleville discovered a flaw in the fd_locked_ioctl function in the floppy driver in the Linux kernel. The floppy driver copies a kernel pointer to user memory in response to the FDGETPRM ioctl. A local user with access to a floppy drive device can take advantage of this flaw to discover the location kernel code and data.
CVE-2018-9363
It was discovered that the Bluetooth HIDP implementation did not correctly check the length of received report messages. A paired HIDP device could use this to cause a buffer overflow, leading to denial of service (memory corruption or crash) or potentially remote code execution.
CVE-2018-9516
It was discovered that the HID events interface in debugfs did not correctly limit the length of copies to user buffers. A local user with access to these files could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.
However, by default debugfs is only accessible by the root user.
CVE-2018-10902
It was discovered that the rawmidi kernel driver does not protect against concurrent access which leads to a double-realloc (double free) flaw. A local attacker can take advantage of this issue for privilege escalation.
CVE-2018-10938
Yves Younan from Cisco reported that the Cipso IPv4 module did not correctly check the length of IPv4 options. On custom kernels with CONFIG_NETLABEL enabled, a remote attacker could use this to cause a denial of service (hang).
CVE-2018-13099
Wen Xu from SSLab at Gatech reported a use-after-free bug in the F2FS implementation. An attacker able to mount a crafted F2FS volume could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.
CVE-2018-14609
Wen Xu from SSLab at Gatech reported a potential NULL pointer dereference in the F2FS implementation. An attacker able to mount arbitrary F2FS volumes could use this to cause a denial of service (crash).
CVE-2018-14617
Wen Xu from SSLab at Gatech reported a potential NULL pointer dereference in the HFS+ implementation. An attacker able to mount arbitrary HFS+ volumes could use this to cause a denial of service (crash).
CVE-2018-14633
Vincent Pelletier discovered a stack-based buffer overflow flaw in the chap_server_compute_md5() function in the iSCSI target code. An unauthenticated remote attacker can take advantage of this flaw to cause a denial of service or possibly to get a non-authorized access to data exported by an iSCSI target.
CVE-2018-14678
M. Vefa Bicakci and Andy Lutomirski discovered a flaw in the kernel exit code used on amd64 systems running as Xen PV guests. A local user could use this to cause a denial of service (crash).
CVE-2018-14734
A use-after-free bug was discovered in the InfiniBand communication manager. A local user could use this to cause a denial of service (crash or memory corruption) or possible for privilege escalation.
CVE-2018-15572
Esmaiel Mohammadian Koruyeh, Khaled Khasawneh, Chengyu Song, and Nael Abu-Ghazaleh, from University of California, Riverside, reported a variant of Spectre variant 2, dubbed SpectreRSB. A local user may be able to use this to read sensitive information from processes owned by other users.
CVE-2018-15594
Nadav Amit reported that some indirect function calls used in paravirtualised guests were vulnerable to Spectre variant 2. A local user may be able to use this to read sensitive information from the kernel.
CVE-2018-16276
Jann Horn discovered that the yurex driver did not correctly limit the length of copies to user buffers. A local user with access to a yurex device node could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.
CVE-2018-16658
It was discovered that the cdrom driver does not correctly validate the parameter to the CDROM_DRIVE_STATUS ioctl. A user with access to a cdrom device could use this to read sensitive information from the kernel or to cause a denial of service (crash).
CVE-2018-17182
Jann Horn discovered that the vmacache_flush_all function mishandles sequence number overflows. A local user can take advantage of this flaw to trigger a use-after-free, causing a denial of service (crash or memory corruption) or privilege escalation.
For Debian 8 'Jessie', these problems have been fixed in version 4.9.110-3+deb9u5~deb8u1.
We recommend that you upgrade your linux-4.9 packages.
