CWE
  • CWE-675 - Multiple Operations on Resource in Single-Operation Context
Summary
In GnuPG before 2.4.9, armor_filter in g10/armor.c has two increments of an index variable where one is intended, leading to an out-of-bounds write for crafted input. (For ExtendedLTS, 2.2.51 and later are fixed versions.)

CVE-2025-68972 (GCVE-0-2025-68972)
Vulnerability from cvelistv5
Published
2025-12-27 22:52
Modified
2026-01-02 20:44
Severity ?
5.9 (Medium) - CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N
CWE
  • CWE-347 - Improper Verification of Cryptographic Signature
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.

CWE
  • n/a
Summary
Libgcrypt before 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm, and the window size is not chosen appropriately. This, for example, affects use of ElGamal in OpenPGP.

CVE-2017-7526 (GCVE-0-2017-7526)
Vulnerability from cvelistv5
Published
2018-07-26 13:00
Modified
2025-12-17 22:06
Severity ?
6.1 (Medium) - CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N
CWE
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.
