Summary
It was discovered that nginx incorrectly handled certain configurations
using the alias directive together with rewrite rules. A remote attacker
could possibly use this issue to cause nginx to crash, resulting in a
denial of service, or execute arbitrary code.
(CVE-2026-15176)
It was discovered that nginx incorrectly handled map directives using
regex matching under certain circumstances. A remote attacker could
possibly use this issue to cause nginx to crash, resulting in a denial
of service, or execute arbitrary code.
(CVE-2026-93479)
It was discovered that nginx incorrectly handled HTTP/3 requests when
proxy_request_buffering was enabled. This issue only affected
Ubuntu 26.04 LTS and Ubuntu 26.10. A remote attacker could possibly use
this issue to inject data into proxied requests.
(CVE-2026-95101)
It was discovered that nginx incorrectly handled asynchronous file I/O
in certain configurations with Server Side Includes pages. A remote
attacker could possibly use this issue to cause nginx to crash,
resulting in a denial of service, or execute arbitrary code.
(CVE-2026-97205)
It was discovered that nginx incorrectly handled SSL session ticket keys
when configured with a shared session cache but without explicit ticket
key rotation. This issue only affected Ubuntu 24.04 LTS, Ubuntu 26.04 LTS,
and Ubuntu 26.10. A remote attacker
could possibly use this issue to forge client SSL sessions and bypass
client certificate verification.
(CVE-2026-97629)
