In the Linux kernel, the following vulnerability has been resolved: iavf: Fixed a use-after-free in freenetdev. We perform netifnapiadd for all allocated qvectors, but potentially also perform netifnapidel for some of them. Then, we call kfree on the qvectors, leaving invalid pointers in...

Astra Linux – Vulnerability in openssl1.0

There is an overflow bug in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are...
