If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, 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 with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q).

Netatalk before 3.1.12 is vulnerable to an out of bounds write in dsi_opensess.c. This is due to lack of bounds checking on attacker controlled data. A remote unauthenticated attacker can leverage this vulnerability to achieve arbitrary code execution.

The HPE-provided Windows firmware installer for certain Gen9, Gen8, G7,and G6 HPE servers allows local disclosure of privileged information. This issue was resolved in previously provided firmware updates as follows. The HPE Windows firmware installer was updated in the system ROM updates which also addressed the original Spectre/Meltdown set of vulnerabilities. At that time, the Windows firmware installer was also updated in the versions of HPE Integrated Lights-Out 2, 3, and 4 (iLO 2, 3, and 4) listed in the security bulletin. The updated HPE Windows firmware installer was released in the system ROM and HPE Integrated Lights-Out (iLO) releases documented in earlier HPE Security Bulletins: HPESBHF03805, HPESBHF03835, HPESBHF03831. Windows-based systems that have already been updated to the system ROM or iLO versions described in these security bulletins require no further action.

The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size.

OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c.

Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service.

Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis.

In Schneider Electric Evlink Charging Station versions prior to v3.2.0-12_v1, the Web Interface has an issue that may allow a remote attacker to gain administrative privileges without properly authenticating remote users.

Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.

OpenSLP releases in the 1.0.2 and 1.1.0 code streams have a heap-related memory corruption issue which may manifest itself as a denial-of-service or a remote code-execution vulnerability.
