An update that fixes 6 vulnerabilities is now available.
Description:
This update for the Linux Kernel 4.4.180-94_130 fixes several issues.
The following security issues were fixed:
- CVE-2020-0429: In l2tp_session_delete and related functions of
l2tp_core.c, there is possible memory corruption due to a use after
free. This could lead to local escalation of privilege with system
execution privileges needed. User interaction is not needed for
exploitation. (bsc#1176724)
- CVE-2020-14381: Fixed a use-after-free in the fast user mutex (futex)
wait operation, which could have lead to memory corruption and possibly
privilege escalation (bsc#1176011).
- CVE-2020-0431: In kbd_keycode of keyboard.c, there is a possible out of
bounds write due to a missing bounds check. This could lead to local
escalation of privilege with no additional execution privileges needed.
User interaction is not needed for exploitation. (bsc#1176722)
- CVE-2020-25212: A TOCTOU mismatch in the NFS client code could be used
by local attackers to corrupt memory or possibly have unspecified other
impact because a size check is in fs/nfs/nfs4proc.c instead of
fs/nfs/nfs4xdr.c (bsc#1176381).
- CVE-2020-11668: Fixed an out of bounds write to the heap in
drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink camera USB
driver) caused by mishandling invalid descriptors (bsc#1168952).
- CVE-2020-1749: A flaw was found in the implementation of some networking
protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an
encrypted tunnel is created between two hosts, the kernel isn't
correctly routing tunneled data over the encrypted link, rather sending
the data unencrypted. This would have allowed anyone in between the two
endpoints to read the traffic unencrypted. (bsc#1165629)
