USN-6967-1: Intel Microcode vulnerabilities

Read Time:50 Second

It was discovered that some Intel® Core™ Ultra Processors did not properly
isolate the stream cache. A local authenticated user could potentially use
this to escalate their privileges. (CVE-2023-42667)

It was discovered that some Intel® Processors did not properly isolate the
stream cache. A local authenticated user could potentially use this to
escalate their privileges. (CVE-2023-49141)

It was discovered that some Intel® Processors did not correctly transition
between the executive monitor and SMI transfer monitor (STM). A privileged
local attacker could use this to escalate their privileges.
(CVE-2024-24853)

It was discovered that some 3rd, 4th, and 5th Generation Intel® Xeon®
Processors failed to properly implement a protection mechanism. A local
attacker could use this to potentially escalate their privileges.
(CVE-2024-24980)

It was discovered that some 3rd Generation Intel Xeon Scalable Processors
did not properly handle mirrored regions with different values. A
privileged local user could use this to cause a denial of service (system
crash). (CVE-2024-25939)

USN-6966-1: Firefox vulnerabilities

Read Time:1 Minute, 2 Second

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, obtain sensitive
information across domains, or execute arbitrary code. (CVE-2024-7518,
CVE-2024-7521, CVE-2024-7524, CVE-2024-7526, CVE-2024-7527, CVE-2024-7528,
CVE-2024-7529, CVE-2024-7530, CVE-2024-7531)

It was discovered that Firefox did not properly manage certain memory
operations when processing graphics shared memory. An attacker could
potentially exploit this issue to escape the sandbox. (CVE-2024-7519)

Nan Wang discovered that Firefox did not properly handle type check in
WebAssembly. An attacker could potentially exploit this issue to execute
arbitrary code. (CVE-2024-7520)

Irvan Kurniawan discovered that Firefox did not properly check an attribute
value in the editor component, leading to an out-of-bounds read
vulnerability. An attacker could possibly use this issue to cause a denial
of service or expose sensitive information. (CVE-2024-7522)

Rob Wu discovered that Firefox did not properly check permissions when
creating a StreamFilter. An attacker could possibly use this issue to
modify response body of requests on any site using a web extension.

resources, leading to a denial of service. This issue only affected
Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2024-25126)

It was discovered that Rack incorrectly handled certain Range headers. A
remote attacker could possibly use this issue to cause Rack to create
large responses, leading to a denial of service. (CVE-2024-26141)

It was discovered that Rack incorrectly handled certain crafted headers. A
remote attacker could possibly use this issue to cause Rack to consume
resources, leading to a denial of service. (CVE-2024-26146)
