FreeBSD : gnupg -- AEAD key import overflow (f9fa7adc-ee51-11ea-a240-002590acae31)

Importing an OpenPGP key having a preference list for AEAD algorithms will lead to an array overflow and thus often to a crash or other undefined behaviour. Importing an arbitrary key can often easily be triggered by an attacker and thus triggering this bug. Exploiting the bug aside from crashes ...

CVE-2020-25125

GnuPG 2.2.21 and 2.2.22 and Gpg4win 3.1.12 has an array overflow, leading to a crash or possibly unspecified other impact, when a victim imports an attacker's OpenPGP key, and this key has AEAD preferences. The overflow is caused by a g10/key-check.c error. NOTE: GnuPG 2.3.x is unaffected. GnuPG...

Oracle Enterprise Manager Cloud Control (Apr 2020 CPU)

The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the April 2020 CPU advisory. - Perl before 5.26.3 and 5.28.x before 5.28.1 has a buffer overflow via a crafted regular expression that...

SUSE SLES15 Security Update : nodejs10 (SUSE-SU-2020:0104-1)

This update for nodejs10 to version 10.18.0 fixes the following issues : Security issues fixed : CVE-2019-16777, CVE-2019-16776, CVE-2019-16775: Updated npm to 6.13.4, fixing an arbitrary path overwrite and access via 'bin' field bsc1159352. Added support for chacha20-poly1305 for Authenticated...

Shadowsocks-libev ss-server UdpRelay Denial-of-Service Vulnerability

Summary An exploitable denial-of-service vulnerability exists in the UDPRelay functionality of Shadowsocks-libev 3.3.2. When utilizing a Stream Cipher and a localaddress, arbitrary UDP packets can cause a FATAL error code path and exit. An attacker can send arbitrary UDP packets to trigger this...

EulerOS 2.0 SP5 : openssl110h (EulerOS-SA-2019-1890)

According to the versions of the openssl110h packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce...

CVE-2019-1543

ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value IV should be 96 bits 12 bytes. OpenSSL allows a variable nonce length and front pads the nonce with 0 bytes if it is less than 12 bytes. However it also...

Internet Bug Bounty: ChaCha20-Poly1305 with long nonces

This report relates to CVE-2019-1543, https://www.openssl.org/news/secadv/20190306.txt, which I reported to the OpenSSL maintainers a few days ago. OpenSSL accepts nonces for the AEAD cipher ChaCha20-Poly1305 of up to 16-bytes. This support is advertised in the OpenSSL documentation and via the...

CVE-2019-1543

CVE-2019-1543 describes a nonce handling flaw in ChaCha20-Poly1305 within OpenSSL: accepting non-default nonce lengths up to 16 bytes with only the last 12 bytes considered, risking nonce reuse if an application sets a longer nonce and changes leading bytes. OpenSSL 1.1.1 and 1.1.0 are affected. ...

0-byte record padding oracle

If an application encounters a fatal protocol error and then calls SSLshutdown twice once to send a closenotify, and once to receive one then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received...

Fedora 28 : python-cryptography / python-cryptography-vectors (2018-a9fe5e183e)
