Astra Linux – Vulnerability in Thunderbird

Thunderbird unprotects a secret OpenPGP key before using it for decryption, signing, or key import tasks. If the task fails, the secret key may remain in memory in an unprotected state. This vulnerability affects Thunderbird versions earlier than 78.8.1...

Astra Linux – Vulnerability in Thunderbird

When receiving an email message signed with OpenPGP/MIME and containing an additional outer MIME message layer, such as a message footer added by a mailing list gateway, Thunderbird only considers the signed inner message for signature validity. This creates the false impression that the addition...

Astra Linux – Vulnerability in Thunderbird

If a MIME-encoded email contains an OpenPGP inline signed or encrypted message part, but also contains an additional unprotected part, Thunderbird did not indicate that only certain parts of the message are protected. This vulnerability affects Thunderbird versions earlier than 78.10.2...

Astra Linux – Vulnerability in Thunderbird

If a Thunderbird user has previously imported Alice’s OpenPGP key, and Alice has extended the validity period of her key, but Alice’s updated key has not yet been imported, an attacker may send an email containing a crafted version of Alice’s key with an invalid subkey. In this case, Thunderbird...

Astra Linux – Vulnerability in libgcrypt20

The ElGamal implementation in Libgcrypt before version 1.9.4 allows plaintext recovery. This occurs because, during interaction between two cryptographic libraries, a dangerous combination of elements arises—specifically, the prime number defined by the receiver’s public key, the generator define...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the AEADEncDataPacket parser in AEADEncDataPacket.java. An attacker can crash packet parsing by supplying an AEAD-encrypted OpenPGP packet with an out-of-range chunk size valu...

UBUNTU-CVE-2026-2625

A flaw was found in rust-rpm-sequoia. An attacker can exploit this vulnerability by providing a specially crafted Red Hat Package Manager RPM file. During the RPM signature verification process, this crafted file can trigger an error in the OpenPGP signature parsing code, leading to an...
