An attacker...

CVE-2022-1197

When importing a revoked key that specified key compromise as the revocation reason, Thunderbird did not update the existing copy of the key that was not yet revoked, and the existing key was kept as non-revoked. Revocation statements that used another revocation reason, or that didn't specify a...

CVE-2022-3775

When rendering certain unicode sequences, grub2's font code doesn't proper validate if the informed glyph's width and height is constrained within bitmap size. As consequence an attacker can craft an input which will lead to a out-of-bounds write into grub2's heap, leading to memory corruption an...

CVE-2017-7374

Use-after-free vulnerability in fs/crypto/ in the Linux kernel before 4.10.7 allows local users to cause a denial of service NULL pointer dereference or possibly gain privileges by revoking keyring keys being used for ext4, f2fs, or ubifs encryption, causing cryptographic transform objects to be...

Fedora Core 1 : gnupg-1.2.3-2 (2003-025)

Phong Nguyen identified a severe bug in the way GnuPG creates and uses ElGamal keys, when those keys are used both to sign and encrypt data. This vulnerability can be used to trivially recover the private key. While the default behavior of GnuPG when generating keys does not lead to the creation ...

GnuPG creates ElGamal keys for signing using insufficient entropy

Overview Gnu Privacy Guard GnuPG is a cryptographic utility used to generate cryptographic keys and perform other cryptographic functions. A vulnerability in the way GnuPG generates ElGamal keys has been discovered. This vulnerability renders ElGamal signing key untrustworthy. Description A...

Important: Red Hat Security Advisory: : Updated gnupg packages disable ElGamal keys

Updated gnupg packages are now available for Red Hat Linux. These updates disable the ability to generate ElGamal keys used for both signing and encrypting and disable the ability to use ElGamal public keys for encrypting data. GnuPG is a utility for encrypting data and creating digital signature...
