nss: ECDSA timing attack mitigation bypass

A flaw was found in nss. Using the EM side-channel, it is possible to extract the position of zero and non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature generation, leaking partial information about the ECDSA nonce. Given a small number of ECDS...

nss: Side channel vulnerabilities during RSA key generation

A flaw was found in NSS, where it is vulnerable to RSA key generation cache timing side-channel attacks. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover the private key. The highest threat to this flaw is to confidentiality...

kernel: memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c allows DoS

A flaw was found in the Linux kernel. The Wireless configuration API functionality mishandles resource cleanup in nl80211getftmresponderstats function. An attacker able to trigger the resource cleanup code path could use this flaw to crash the system. The highest threat from this vulnerability is...
