CVE-2015-1606 2 Debian, Gnupg 2 Debian Linux, Gnupg 2019-11-22 4.3 MEDIUM 5.5 MEDIUM
The keyring DB in GnuPG before 2.1.2 does not properly handle invalid packets, which allows remote attackers to cause a denial of service (invalid read and use-after-free) via a crafted keyring file.
CVE-2015-1607 2 Canonical, Gnupg 2 Ubuntu Linux, Gnupg 2019-11-22 4.3 MEDIUM 5.5 MEDIUM
kbx/keybox-search.c in GnuPG before 1.4.19, 2.0.x before 2.0.27, and 2.1.x before 2.1.2 does not properly handle bitwise left-shifts, which allows remote attackers to cause a denial of service (invalid read operation) via a crafted keyring file, related to sign extensions and "memcpy with overlapping ranges."
CVE-2017-7526 3 Canonical, Debian, Gnupg 3 Ubuntu Linux, Debian Linux, Libgcrypt 2019-10-09 4.3 MEDIUM 6.8 MEDIUM
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.
CVE-2018-9234 2 Canonical, Gnupg 2 Ubuntu Linux, Gnupg 2019-02-27 5.0 MEDIUM 7.5 HIGH
GnuPG 2.2.4 and 2.2.5 does not enforce a configuration in which key certification requires an offline master Certify key, which results in apparently valid certifications that occurred only with access to a signing subkey.
CVE-2018-1000858 2 Canonical, Gnupg 2 Ubuntu Linux, Gnupg 2019-02-13 6.8 MEDIUM 8.8 HIGH
GnuPG version 2.1.12 - 2.2.11 contains a Cross ite Request Forgery (CSRF) vulnerability in dirmngr that can result in Attacker controlled CSRF, Information Disclosure, DoS. This attack appear to be exploitable via Victim must perform a WKD request, e.g. enter an email address in the composer window of Thunderbird/Enigmail. This vulnerability appears to have been fixed in after commit 4a4bb874f63741026bd26264c43bb32b1099f060.
CVE-2017-0379 2 Debian, Gnupg 2 Debian Linux, Libgcrypt 2019-01-16 5.0 MEDIUM 7.5 HIGH
Libgcrypt before 1.8.1 does not properly consider Curve25519 side-channel attacks, which makes it easier for attackers to discover a secret key, related to cipher/ecc.c and mpi/ec.c.
CVE-2017-9526 1 Gnupg 1 Libgcrypt 2019-01-16 4.3 MEDIUM 5.9 MEDIUM
In Libgcrypt before 1.7.7, an attacker who learns the EdDSA session key (from side-channel observation during the signing process) can easily recover the long-term secret key. 1.7.7 makes a cipher/ecc-eddsa.c change to store this session key in secure memory, to ensure that constant-time point operations are used in the MPI library.
CVE-2013-4242 4 Canonical, Debian, Gnupg and 1 more 5 Ubuntu Linux, Debian Linux, Gnupg and 2 more 2018-10-30 1.9 LOW N/A
GnuPG before 1.4.14, and Libgcrypt before 1.5.3 as used in GnuPG 2.0.x and possibly other products, allows local users to obtain private RSA keys via a cache side-channel attack involving the L3 cache, aka Flush+Reload.
CVE-2014-4617 3 Debian, Gnupg, Opensuse 3 Debian Linux, Gnupg, Opensuse 2018-10-30 5.0 MEDIUM N/A
The do_uncompress function in g10/compress.c in GnuPG 1.x before 1.4.17 and 2.x before 2.0.24 allows context-dependent attackers to cause a denial of service (infinite loop) via malformed compressed packets, as demonstrated by an a3 01 5b ff byte sequence.
CVE-2006-3082 1 Gnupg 1 Gnupg 2018-10-18 5.0 MEDIUM N/A
parse-packet.c in GnuPG (gpg) 1.4.3 and 1.9.20, and earlier versions, allows remote attackers to cause a denial of service (gpg crash) and possibly overwrite memory via a message packet with a large length (long user ID string), which could lead to an integer overflow, as demonstrated using the --no-armor option.
CVE-2006-6169 1 Gnupg 1 Gnupg 2018-10-17 6.8 MEDIUM N/A
Heap-based buffer overflow in the ask_outfile_name function in openfile.c for GnuPG (gpg) 1.4 and 2.0, when running interactively, might allow attackers to execute arbitrary code via messages with "C-escape" expansions, which cause the make_printable_string function to return a longer string than expected while constructing a prompt.
CVE-2006-3746 1 Gnupg 1 Gnupg 2018-10-17 5.0 MEDIUM N/A
Integer overflow in parse_comment in GnuPG (gpg) 1.4.4 allows remote attackers to cause a denial of service (segmentation fault) via a crafted message.
CVE-2007-1263 2 Gnu, Gnupg 2 Gpgme, Gnupg 2018-10-16 5.0 MEDIUM N/A
GnuPG 1.4.6 and earlier and GPGME before 1.1.4, when run from the command line, does not visually distinguish signed and unsigned portions of OpenPGP messages with multiple components, which might allow remote attackers to forge the contents of a message without detection.
CVE-2016-6313 3 Canonical, Debian, Gnupg 4 Ubuntu Linux, Debian Linux, Gnupg and 1 more 2018-01-04 5.0 MEDIUM 5.3 MEDIUM
The mixing functions in the random number generator in Libgcrypt before 1.5.6, 1.6.x before 1.6.6, and 1.7.x before 1.7.3 and GnuPG before 1.4.21 make it easier for attackers to obtain the values of 160 bits by leveraging knowledge of the previous 4640 bits.
CVE-2014-5270 2 Debian, Gnupg 2 Debian Linux, Libgcrypt 2017-11-03 2.1 LOW N/A
Libgcrypt before 1.5.4, as used in GnuPG and other products, does not properly perform ciphertext normalization and ciphertext randomization, which makes it easier for physically proximate attackers to conduct key-extraction attacks by leveraging the ability to collect voltage data from exposed metal, a different vector than CVE-2013-4576.
CVE-2013-4576 1 Gnupg 1 Gnupg 2017-08-28 2.1 LOW N/A
GnuPG 1.x before 1.4.16 generates RSA keys using sequences of introductions with certain patterns that introduce a side channel, which allows physically proximate attackers to extract RSA keys via a chosen-ciphertext attack and acoustic cryptanalysis during decryption. NOTE: applications are not typically expected to protect themselves from acoustic side-channel attacks, since this is arguably the responsibility of the physical device. Accordingly, issues of this type would not normally receive a CVE identifier. However, for this issue, the developer has specified a security policy in which GnuPG should offer side-channel resistance, and developer-specified security-policy violations are within the scope of CVE.
CVE-2008-1530 1 Gnupg 1 Gnupg 2017-08-07 9.3 HIGH N/A
GnuPG (gpg) 1.4.8 and 2.0.8 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted duplicate keys that are imported from key servers, which triggers "memory corruption around deduplication of user IDs."
CVE-2015-7511 3 Canonical, Debian, Gnupg 3 Ubuntu Linux, Debian Linux, Libgcrypt 2017-06-30 1.9 LOW 2.0 LOW
Libgcrypt before 1.6.5 does not properly perform elliptic-point curve multiplication during decryption, which makes it easier for physically proximate attackers to extract ECDH keys by measuring electromagnetic emanations.
CVE-2013-4402 2 Canonical, Gnupg 2 Ubuntu Linux, Gnupg 2014-01-03 5.0 MEDIUM N/A
The compressed packet parser in GnuPG 1.4.x before 1.4.15 and 2.0.x before 2.0.22 allows remote attackers to cause a denial of service (infinite recursion) via a crafted OpenPGP message.
CVE-2013-4351 1 Gnupg 1 Gnupg 2014-01-03 5.8 MEDIUM N/A
GnuPG 1.4.x, 2.0.x, and 2.1.x treats a key flags subpacket with all bits cleared (no usage permitted) as if it has all bits set (all usage permitted), which might allow remote attackers to bypass intended cryptographic protection mechanisms by leveraging the subkey.
