 ------------------------------------------------------------------------- Debian LTS Advisory DLA-3410-1 [email protected] https://www.debian.org/lts/security/ Guilhem Moulin May 01, 2023 https://wiki.debian.org/LTS
 -------------------------------------------------------------------------

 Package : openvswitch Version : 2.10.7+ds1-0+deb10u4 CVE ID : CVE-2023-1668 Debian Bug : 1034042

 David Marchand discovered that Open vSwitch, a multilayer, software-based, Ethernet virtual switch, was vulnerable to crafted IP packets with ip proto set to 0, potentially causing a denial of service.

 Triggering the vulnerability requires an attacker to send a crafted IP packet with protocol field set to 0 and the flow rules to contain 'set' actions on other fields in the IP protocol header. The resulting flows will omit required actions, and fail to mask the IP protocol field, resulting in a large bucket which captures all IP packets.

 For Debian 10 buster, this problem has been fixed in version 2.10.7+ds1-0+deb10u4.

 We recommend that you upgrade your openvswitch packages.
