CVSS: 5.5EPSS: 0%CPEs: 32EXPL: 2CVE-2021-3744 – kernel: crypto: ccp - fix resource leaks in ccp_run_aes_gcm_cmd()
https://notcve.org/view.php?id=CVE-2021-3744
A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808. Se ha encontrado un fallo de pérdida de memoria en el kernel de Linux en la función ccp_run_aes_gcm_cmd() en el archivo drivers/crypto/ccp/ccp-ops.c, que permite a atacantes causar una denegación de servicio (consumo de memoria). Esta vulnerabilidad es similar a la anterior CVE-2019-18808 A flaw was found in the Linux kernel. A memory leak in the ccp-ops crypto driver can allow attackers to cause a denial of service. • http://www.openwall.com/lists/oss-security/2021/09/14/1 https://bugzilla.redhat.com/show_bug.cgi?id=2000627 https://github.com/torvalds/linux/commit/505d9dcb0f7ddf9d075e729523a33d38642ae680 https://kernel.googlesource.com/pub/scm/linux/kernel/git/herbert/crypto-2.6/+/505d9dcb0f7ddf9d075e729523a33d38642ae680%5E%21/#F0 https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7BLLVKYAIETEORUPTFO3TR3C33ZPFXQM https: • CWE-401: Missing Release of Memory after Effective Lifetime •

An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. Se ha detectado un problema en el kernel de Linux versiones anteriores a 5.14.15. Se presenta un fallo de índice de matriz fuera de límites en la función detach_capi_ctr en el archivo drivers/isdn/capi/kcapi.c An improper validation of an array index and out of bounds memory read in the Linux kernel's Integrated Services Digital Network (ISDN) functionality was found in the way users call ioctl CMTPCONNADD. A local user could use this flaw to crash the system or starve the resources causing denial of service. • http://www.openwall.com/lists/oss-security/2021/11/05/1 https://bugzilla.redhat.com/show_bug.cgi?id=2013180 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.14.15 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1f3e2e97c003f80c4b087092b225c8787ff91e4d https://lists.debian.org/debian-lts-announce/2021/12/msg00012.html https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://lore.kernel.org/netdev/CAFcO6XOvGQrRTaTkaJ0p3zR7y7nrAWD79r48 • CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 0CVE-2021-38507 – Mozilla: Opportunistic Encryption in HTTP2 could be used to bypass the Same-Origin-Policy on services hosted on other ports
https://notcve.org/view.php?id=CVE-2021-38507
The Opportunistic Encryption feature of HTTP2 (RFC 8164) allows a connection to be transparently upgraded to TLS while retaining the visual properties of an HTTP connection, including being same-origin with unencrypted connections on port 80. However, if a second encrypted port on the same IP address (e.g. port 8443) did not opt-in to opportunistic encryption; a network attacker could forward a connection from the browser to port 443 to port 8443, causing the browser to treat the content of port 8443 as same-origin with HTTP. This was resolved by disabling the Opportunistic Encryption feature, which had low usage. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. La funcionalidad Opportunistic Encryption de HTTP2 (RFC 8164) permite que una conexión sea actualizada transparentemente a TLS mientras conserva las propiedades visuales de una conexión HTTP, incluyendo el mismo origen con conexiones no cifradas en el puerto 80. • https://bugzilla.mozilla.org/show_bug.cgi?id=1730935 https://lists.debian.org/debian-lts-announce/2021/12/msg00030.html https://lists.debian.org/debian-lts-announce/2022/01/msg00001.html https://security.gentoo.org/glsa/202202-03 https://security.gentoo.org/glsa/202208-14 https://www.debian.org/security/2021/dsa-5026 https://www.debian.org/security/2022/dsa-5034 https://www.mozilla.org/security/advisories/mfsa2021-48 https://www.mozilla.org/security/advisories/mfsa2021-49 • CWE-346: Origin Validation Error CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
