strongswan security update
The strongSwan IPsec implementation supports both the IKEv1 and IKEv2 key exchange protocols in conjunction with the native NETKEY IPsec stack of the Linux kernel. Security Fix(es): In the eap-mschapv2 plugin (client-side) in strongSwan before 6.0.3, a malicious EAP-MSCHAPv2 server can send a crafted message of size 6 through 8, and cause an integer underflow that potentially results in a heap-based buffer overflow.(CVE-2025-62291)
