Debian LTS Advisory DLA-2444-1 [email protected]
https://www.debian.org/lts/security/ Utkarsh Gupta
November 10, 2020 https://wiki.debian.org/LTS
Package : tcpdump
Version : 4.9.3-1~deb9u2
CVE ID : CVE-2020-8037
Debian Bug : 973877
The ppp de-capsulator in tcpdump 4.9.3 can be convinced to allocate
a large amount of memory.
The buffer should be big enough to hold the captured data, but it
doesnβt need to be big enough to hold the entire on-the-network
packet, if we havenβt captured all of it.
For Debian 9 stretch, this problem has been fixed in version
4.9.3-1~deb9u2.
We recommend that you upgrade your tcpdump packages.
For the detailed security status of tcpdump please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/tcpdump
