OpenSSL: Double-free in DSA code

A double-free flaw was found in the way OpenSSL parsed certain malformed DSA Digital Signature Algorithm private keys. An attacker could create specially crafted DSA private keys that, when processed by an application compiled against OpenSSL, could cause the application to crash...

bouncycastle: DSA does not fully validate ASN.1 encoding during signature verification allowing for injection of unsigned data

In Bouncy Castle JCE Provider version 1.55 and earlier the DSA does not fully validate ASN.1 encoding of signature on verification. It is possible to inject extra elements in the sequence making up the signature and still have it validate, which in some cases may allow the introduction of...

openssl: BN_mod_exp may produce incorrect results on x86_64

There is a carry propagating bug in the x8664 Montgomery squaring procedure in OpenSSL 1.0.2 before 1.0.2k and 1.1.0 before 1.1.0d. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed...

CVE-2018-10988

CVE-2018-10988 affects Diqee Diqee360 devices. The firmware update process at boot reads an unsigned script from the microSD (upgrade.sh) and executes it as root, in /mnt/sdcard/$PRO_NAME/upgrade.sh or /sdcard/upgrage_360/upgrade.sh, without signature verification.
