In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a particular sequence of operations that includes creation of a new virtual machine control block (VMCB). The failure to flush the TLB may cause the microcode to use stale TLB translations which may allow for disclosure of SEV guest memory contents. Users of SEV-ES/SEV-SNP guest VMs are not impacted by this vulnerability.
TOCTOU (time-of-check to time-of-use) issue in the System Management Unit (SMU) may result in a DMA (Direct Memory Access) to invalid DRAM address that could result in denial of service.
Failure to flush the Translation Lookaside Buffer (TLB) of the I/O memory management unit (IOMMU) may lead an IO device to write to memory it should not be able to access, resulting in a potential loss of integrity.
golang-1.17.7-1.el7
Update to 1.17.7, including fixes for CVE-2021-29923, CVE-2021-43565, CVE-2022-23806, CVE-2022-23772, and CVE-2022-23773
Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, spoof the
browser UI, bypass permission prompts, obtain sensitive information,
bypass security restrictions, or execute arbitrary code.

hsts: ignore trailing dots when comparing hosts names (CVE-2022-30115)
reject percent-encoded path separator in URL host (CVE-2022-27780)
Axel Chong discovered that curl incorrectly handled percent-encoded URL
separators. A remote attacker could possibly use this issue to trick curl
into using the wrong URL and bypass certain checks or filters. This issue
only affected Ubuntu 22.04 LTS. (CVE-2022-27780)
Florian Kohnhuser discovered that curl incorrectly handled returning a
TLS server’s certificate chain details. A remote attacker could possibly
use this issue to cause curl to stop responding, resulting in a denial of
service. (CVE-2022-27781)
Harry Sintonen discovered that curl incorrectly reused a previous
connection when certain options had been changed, contrary to expectations.
(CVE-2022-27782)
An issue was found in bludit v3.13.0, unsafe implementation of the backup plugin allows attackers to upload arbitrary files.
