libreswan: vulnerability in the processing of IKEv1 informational packets due to missing integrity check
A vulnerability was found in the Libreswan Project. It was discovered that libreswan, strongswan, and openswan did not verify the integrity check value for received IKEv1 Informational Exchange packets...
[SECURITY] Fedora 30 Update: libreswan-3.29-1.fc30
Libreswan is a free implementation of IPsec & IKE for Linux. IPsec is the Internet Protocol Security and uses strong cryptography to provide both authentication and encryption services. These services allow you to build secure tunnels through untrusted networks. Everything passing through the...
Remote Code Execution (RCE)
openswan is vulnerable to remote code execution RCE attacks. The vulnerability exists through a buffer overflow issue in the atodn function in Openswan before 2.6.39, when Opportunistic Encryption is enabled and an RSA key is being used, allows remote attackers to cause a denial of service pluto...
CVE-2018-15836
In verifysignedhash in lib/liboswkeys/signatures.c in Openswan before 2.6.50.1, the RSA implementation does not verify the value of padding string during PKCS1 v1.5 signature verification. Consequently, a remote attacker can forge signatures when small public exponents are being used. IKEv2...

CVE-2018-15836
CVE-2018-15836 affects Openswan before 2.6.50.1. In verify_signed_hash() (lib/liboswkeys/signatures.c), the RSA PKCS#1 v1.5 padding value is not verified during signature verification, enabling signature forgery when small public exponents are used. IKEv2 signature verification is affected when R...

PT-2018-13228
Name of the Vulnerable Software and Affected Versions Openswan versions prior to 2.6.50.1 Description The issue concerns the RSA implementation in the verify signed hash function, which fails to verify the padding string value during PKCS1 v1.5 signature verification. This allows a remote attacke...
