DEBIAN-CVE-2020-16119
Use-after-free vulnerability in the Linux kernel exploitable by a local attacker due to reuse of a DCCP socket with an attached dccpshctxccid object as a listener after being released. Fixed in Ubuntu Linux kernel 5.4.0-51.56, 5.3.0-68.63, 4.15.0-121.123, 4.4.0-193.224, 3.13.0.182.191 and...
The vulnerability of the dccp_printOption() function in the tcpdump utility for capturing and analyzing network traffic allows a hacker to induce a service failure.
The vulnerability of the dccpprintOption function print-dccp.c in the packet capture and analysis tool tcpdump is related to buffer-over-read operations in memory. Exploiting this vulnerability could allow a remote attacker to cause a service failure...
tcpdump: Buffer over-read in dccp_print_option() function in print-dccp.c
An out-of-bounds read vulnerability was discovered in tcpdump while printing DCCP packets captured in a pcap file or coming from the network. A remote attacker may abuse this flaw by sending specially crafted packets that, when printed, would trigger the flaw and crash the application...
USN-4577-1 linux-hwe, linux-gke-5.0, linux-gke-5.3, linux-oem-osp1, linux-raspi2-5.3 vulnerabilities
Hadar Manor discovered that the DCCP protocol implementation in the Linux kernel improperly handled socket reuse, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2020-16119 Giuseppe Scriva...
