CVE-2017-3731
CVSS v2.0
7.8
High
| Vector | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
OpenSSL versions 1.0.2 through 1.0.2k
OpenSSL versions 1.1.0 through 1.1.0d
MySQL Server versions 5.6.35 and earlier
MySQL Server versions 5.7.18 and earlier
Description
The issue is related to an out-of-bounds read in the OpenSSL library when using specific ciphers, such as CHACHA20/POLY1305 or RC4-MD5, on a 32-bit host. This can cause a server or client to crash when a truncated packet is received. A remote attacker could exploit this vulnerability to cause a denial of service.
Recommendations
For OpenSSL version 1.1.0, update to 1.1.0d.
For OpenSSL version 1.0.2, update to 1.0.2k if the RC4-MD5 algorithm has not been disabled.
For MySQL Server versions 5.6.35 and earlier, and 5.7.18 and earlier, update to a version that includes the fix for this issue.
As a temporary workaround, consider disabling the use of vulnerable ciphers, such as CHACHA20/POLY1305 or RC4-MD5, until a patch is available.
