High
| Vector | AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
tcpdump versions prior to 4.99.0
tcpdump versions prior to 4.9.3
Description
The issue is related to a buffer overflow in the command-line argument parser of tcpdump, specifically in the
read infile() function in tcpdump.c. This can be triggered by an attacker creating a large file (4GB) on the local filesystem and specifying its name as the value of the -F command-line argument. The vulnerability also involves a buffer overflow and/or over-read in libpcap, as used in tcpdump.Recommendations
For versions prior to 4.99.0, update to version 4.99.0 or later to resolve the issue.
For versions prior to 4.9.3, update to version 4.9.3 or later to resolve the issue.
As a temporary workaround, consider avoiding the use of the
-F command-line argument with large files until a patch is available.Fix
Memory Corruption
Integer Overflow
Out of bounds Read
Buffer Overflow
