Kamil Frankowicz discovered that a number of YARA's functions
generated memory exceptions when processing specially crafted
rules or files. A remote attacker could possibly use these
issues to cause YARA to crash, resulting in a denial of
service. These issues only affected Ubuntu 16.04 LTS.
(CVE-2016-10211, CVE-2017-5923, CVE-2017-5924, CVE-2017-8294,

Jurriaan Bremer discovered that YARA's yr_object_array_set_limit()
function could result in a heap buffer overflow when scanning
specially crafted .NET files. A remote attacker could possibly use
this issue to cause YARA to crash, resulting in a denial of service.
This issue only affected Ubuntu 16.04 LTS. (CVE-2017-11328)
It was discovered that YARA's yr_execute_code() function could
cause an out-of-bounds read or write when parsing specially crafted
compiled rule files. A remote attacker could possibly use these
issues to cause YARA to crash, resulting in a denial of service.
These issues only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.
(CVE-2018-12034, CVE-2018-12035)
It was discovered that YARA's virtual machine could be escaped in
certain instances. A remote attacker could possibly use these issues
to execute arbitrary code. These issues only affected Ubuntu 16.04
LTS and Ubuntu 18.04 LTS. (CVE-2018-19974, CVE-2018-19975,
CVE-2018-19976)
It was discovered that YARA's macho_parse_file() function would
generate an out-of-bounds memory access error when parsing a
specially crafted Mach-O file. A remote attacker could possibly use
this issue to cause YARA to crash, resulting in a denial of service,
or execute arbitrary code. This issue only affected Ubuntu 20.04 LTS.
(CVE-2019-19648)
It was discovered that YARA's macho.c implementation contained several
overflow reads, which could be triggered when parsing specially
crafted Mach-O files. A remote attacker could possibly use this issue
to cause YARA to crash, resulting in a denial of service, or to learn
sensitive information. This issue only affected Ubuntu 20.04 LTS.
(CVE-2021-3402)
It was discovered that YARA's yr_set_configuration() function could
trigger a buffer overflow when parsing specially crafted rules. A
remote attacker could possibly use this issue to cause YARA to crash,
resulting in a denial of service. This issue only affected Ubuntu
18.04 LTS and Ubuntu 20.04 LTS. (CVE-2021-45429)

USN-7968-1 fixed vulnerabilities in Apache HTTP Server. The update
introduced a regression in mod_md where the MDStapleOthers setting was
ignored which resulted in OCSP being broken for some domains. This update
fixes the problem.
We apologize for the inconvenience.
Original advisory details:
It was discovered that the Apache HTTP Server incorrectly handled failed
ACME certificate renewals. This could result in renewal attempts to be
repeated without delays, possibly leading to a denial of service.
(CVE-2025-55753)
Anthony Parfenov discovered that the Apache HTTP Server would pass the
query string to cmd directives when configured with Server Side Includes
(SSI) enabled and mod_cgid. An attacker could possibly use this issue to
execute arbitrary code. (CVE-2025-58098)
Mattias Åsander discovered that the Apache HTTP Server incorrectly
neutralized certain environment variables. This could result in
unexpectedly superseding variables calculated by the server for CGI
programs. (CVE-2025-65082)
Mattias Åsander discovered that the Apache HTTP Server incorrectly
handled AllowOverride FileInfo configurations when using mod_userdir with
suexec. An attacker with access to use the RequestHeader directive in
htaccess can cause some CGI scripts to run under an unexpected userid.
(CVE-2025-66200)

USN-8018-1 fixed vulnerabilities in python3. That update introduced
regressions. The patches for CVE-2025-15366 and CVE-2025-15367 caused
behavior regressions in IMAP and POP3 handling, which upstream chose to
avoid by not backporting them. Additionally, the patch for CVE-2026-0865
incorrectly rejected horizontal tabs in wsgiref headers. This update fixes
these problems.
We apologize for the inconvenience.
Original advisory details:
Denis Ledoux discovered that Python incorrectly parsed email message
headers. An attacker could possibly use this issue to inject arbitrary
headers into email messages. This issue only affected python3.6,
python3.7, python3.8, python3.9, python3.10, python3.11, python3.12,
python3.13, and python3.14 packages. (CVE-2025-11468)
Jacob Walls, Shai Berger, and Natalia Bidart discovered that Python
inefficiently parsed XML input with quadratic complexity. An attacker
could possibly use this issue to cause a denial of service.
(CVE-2025-12084)
It was discovered that Python incorrectly parsed malicious plist files. An
attacker could possibly use this issue to cause Python to use excessive
resources, leading to a denial of service. This issue only affected
python3.5, python3.6, python3.7, python3.8, python3.9, python3.10,
python3.11, python3.12, python3.13, and python3.14 packages.
(CVE-2025-13837)
Omar Hasan discovered that Python incorrectly parsed URL mediatypes. An
attacker could possibly use this issue to inject arbitrary HTTP headers.
(CVE-2025-15282)
Omar Hasan discovered that Python incorrectly parsed malicious IMAP
inputs. An attacker could possibly use this issue to inject arbitrary
IMAP commands. (CVE-2025-15366)
Omar Hasan discovered that Python incorrectly parsed malicious POP3
inputs. An attacker could possibly use this issue to inject arbitrary
POP3 commands. (CVE-2025-15367)
Omar Hasan discovered that Python incorrectly parsed malicious HTTP cookie
headers. An attacker could possibly use this issue to inject arbitrary
HTTP headers. (CVE-2026-0672)
Omar Hasan discovered that Python incorrectly parsed malicious HTTP header
names and values. An attacker could possibly use this issue to inject
arbitrary HTTP headers. (CVE-2026-0865)
