Test Kennung: | 1.3.6.1.4.1.25623.1.1.2.2020.1996 |
Kategorie: | Huawei EulerOS Local Security Checks |
Titel: | Huawei EulerOS: Security Advisory for python-crypto (EulerOS-SA-2020-1996) |
Zusammenfassung: | The remote host is missing an update for the Huawei EulerOS 'python-crypto' package(s) announced via the EulerOS-SA-2020-1996 advisory. |
Beschreibung: | Summary: The remote host is missing an update for the Huawei EulerOS 'python-crypto' package(s) announced via the EulerOS-SA-2020-1996 advisory. Vulnerability Insight: Heap-based buffer overflow in the ALGnew function in block_templace.c in Python Cryptography Toolkit (aka pycrypto) allows remote attackers to execute arbitrary code as demonstrated by a crafted iv parameter to cryptmsg.py.(CVE-2013-7459) lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for PyCrypto's ElGamal implementation.(CVE-2018-6594) Affected Software/OS: 'python-crypto' package(s) on Huawei EulerOS Virtualization for ARM 64 3.0.6.0. Solution: Please install the updated package(s). CVSS Score: 7.5 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P |
