CVE-2026-24881 (GCVE-0-2026-24881)
Vulnerability from cvelistv5 – Published: 2026-01-27 18:36 – Updated: 2026-06-30 12:06
VLAI?
Summary
In GnuPG before 2.5.17, a crafted CMS (S/MIME) EnvelopedData message carrying an oversized wrapped session key can cause a stack-based buffer overflow in gpg-agent during PKDECRYPT--kem=CMS handling. This can easily be leveraged for denial of service; however, there is also memory corruption that could lead to remote code execution.

CVE-2025-68972 (GCVE-0-2025-68972)
Vulnerability from cvelistv5 – Published: 2025-12-27 22:52 – Updated: 2026-01-02 20:44
VLAI?
Summary
In GnuPG through 2.4.8, if a signed message has \f at the end of a plaintext line, an adversary can construct a modified message that places additional text after the signed material, such that signature verification of the modified message succeeds (although an "invalid armor" message is printed during verification). This is related to use of \f as a marker to denote truncation of a long plaintext line.

CVE-2017-7526 (GCVE-0-2017-7526)
Vulnerability from cvelistv5 – Published: 2018-07-26 13:00 – Updated: 2025-12-17 22:06
VLAI?
Summary
libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computation. This side-channel requires that attacker can run arbitrary software on the hardware where the private RSA key is used.
