CVE-2022-24704 (GCVE-0-2022-24704)

Vulnerability from cvelistv5 – Published: 2022-02-14 21:04 – Updated: 2024-09-16 19:00
VLAI?
Summary
The rad_packet_recv function in opt/src/accel-pppd/radius/packet.c suffers from a buffer overflow vulnerability, whereby user input len is copied into a fixed buffer &attr->val.integer without any bound checks. If the client connects to the server and sends a large radius packet, a buffer overflow vulnerability will be triggered.
Severity ?
No CVSS data available.

Vulnerability from cvelistv5 – Published: 2020-09-09 22:45 – Updated: 2024-08-04 13:08
VLAI?
Summary
In ACCEL-PPP (an implementation of PPTP/PPPoE/L2TP/SSTP), there is a buffer overflow when receiving an l2tp control packet ith an AVP which type is a string and no hidden flags, length set to less than 6. If your application is used in open networks or there are untrusted nodes in the network it is highly recommended to apply the patch. The problem was patched with commit 2324bcd5ba12cf28f47357a8f03cd41b7c04c52b As a workaround changes of commit 2324bcd5ba12cf28f47357a8f03cd41b7c04c52b can be applied to older versions.
