Name of the Vulnerable Software and Affected Versions
Corosync versions 3.1.9 and earlier
Description
The issue is a stack-based buffer overflow in the
orf token endian convert function in exec/totemsrp.c via a large UDP packet, which can be exploited if encryption is disabled or the attacker knows the encryption key.Recommendations
For Corosync versions 3.1.9 and earlier, as a temporary workaround, consider disabling the
orf token endian convert function until a patch is available. Restrict access to the vulnerable module to minimize the risk of exploitation. Avoid using large UDP packets in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
