CVE-2023-51765 3 Freebsd, Redhat, Sendmail 3 Freebsd, Enterprise Linux, Sendmail 2024-11-21 N/A 5.3 MEDIUM
sendmail through 8.17.2 allows SMTP smuggling in certain configurations. Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because sendmail supports <LF>.<CR><LF> but some other popular e-mail servers do not. This is resolved in 8.18 and later versions with 'o' in srv_features.
CVE-2023-51764 3 Fedoraproject, Postfix, Redhat 3 Fedora, Postfix, Enterprise Linux 2024-11-21 N/A 5.3 MEDIUM
Postfix through 3.8.5 allows SMTP smuggling unless configured with smtpd_data_restrictions=reject_unauth_pipelining and smtpd_discard_ehlo_keywords=chunking (or certain other options that exist in recent versions). Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because Postfix supports <LF>.<CR><LF> but some other popular e-mail servers do not. To prevent attack variants (by always disallowing <LF> without <CR>), a different solution is required, such as the smtpd_forbid_bare_newline=yes option with a Postfix minimum version of 3.5.23, 3.6.13, 3.7.9, 3.8.4, or 3.9.

CVE-2023-4692 2 Gnu, Redhat 2 Grub2, Enterprise Linux 2024-11-21 N/A 7.5 HIGH
An out-of-bounds write flaw was found in grub2's NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, leading to grub's heap metadata corruption. In some circumstances, the attack may also corrupt the UEFI firmware heap metadata. As a result, arbitrary code execution and secure boot protection bypass may be achieved.
CVE-2023-4641 2 Redhat, Shadow-maint 9 Codeready Linux Builder, Codeready Linux Builder For Arm64, Codeready Linux Builder For Ibm Z Systems and 6 more 2024-11-21 N/A 4.7 MEDIUM
A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. This may allow an attacker with enough access to retrieve the password from the memory.
CVE-2023-4569 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2024-11-21 N/A 5.5 MEDIUM
A memory leak flaw was found in nft_set_catchall_flush in net/netfilter/nf_tables_api.c in the Linux Kernel. This issue may allow a local attacker to cause double-deactivations of catchall elements, which can result in a memory leak.
CVE-2023-4535 3 Fedoraproject, Opensc Project, Redhat 3 Fedora, Opensc, Enterprise Linux 2024-11-21 N/A 4.5 MEDIUM
An out-of-bounds read vulnerability was found in OpenSC packages within the MyEID driver when handling symmetric key encryption. Exploiting this flaw requires an attacker to have physical access to the computer and a specially crafted USB device or smart card. This flaw allows the attacker to manipulate APDU responses and potentially gain unauthorized access to sensitive data, compromising the system's security.
CVE-2023-4503 1 Redhat 3 Enterprise Linux, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Expansion Pack 2024-11-21 N/A 6.8 MEDIUM

CVE-2023-4273 5 Debian, Fedoraproject, Linux and 2 more 12 Debian Linux, Fedora, Linux Kernel and 9 more 2024-11-21 N/A 6.0 MEDIUM
A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation of the file name reconstruction function, which is responsible for reading file name entries from a directory index and merging file name parts belonging to one file into a single long file name. Since the file name characters are copied into a stack variable, a local privileged attacker could use this flaw to overflow the kernel stack.
CVE-2023-4194 4 Debian, Fedoraproject, Linux and 1 more 4 Debian Linux, Fedora, Linux Kernel and 1 more 2024-11-21 N/A 5.5 MEDIUM
A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to bypass network filters and gain unauthorized access to some resources. The original patches fixing CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits - a096ccca6e50 ("tun: tun_chr_open(): correctly initialize socket uid"), - 66b2c338adce ("tap: tap_open(): correctly initialize socket uid"), pass "inode->i_uid" to sock_init_data_uid() as the last parameter and that turns out to not be accurate.
CVE-2023-4156 3 Fedoraproject, Gnu, Redhat 3 Fedora, Gawk, Enterprise Linux 2024-11-21 N/A 4.4 MEDIUM
