DEBIAN-CVE-2017-12153

A security flaw was discovered in the nl80211setrekeydata function in net/wireless/nl80211.c in the Linux kernel through 4.13.3. This function does not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAPNETADMIN capability and...

kernel: Signed overflow for SO_{SND|RCV}BUFFORCE

A flaw was found in the Linux kernel's implementation of setsockopt for the SOSND|RCVBUFFORCE setsockopt system call. Users with non-namespace CAPNETADMIN are able to trigger this call and create a situation in which the sockets sendbuff data size could be negative. This could adversely affect...
