Name of the Vulnerable Software and Affected Versions
libslirp versions 4.3.1 and earlier
Description
The issue is related to a buffer over-read in the slirp.c component of the libslirp TCP-IP emulator. This occurs because the component attempts to read a certain amount of header data, even if it exceeds the total packet length. Exploitation of this issue could allow a remote attacker to access confidential data.
Recommendations
For libslirp versions 4.3.1 and earlier, consider applying a patch or updating to a version where this issue is fixed, if available. As a temporary workaround, consider restricting access to the slirp.c component to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
