CVE-2021-3733 4 Fedoraproject, Netapp, Python and 1 more 20 Extra Packages For Enterprise Linux, Fedora, Hci Compute Node Firmware and 17 more 2025-11-03 4.0 MEDIUM 6.5 MEDIUM
There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability.
CVE-2021-3669 5 Debian, Fedoraproject, Ibm and 2 more 24 Debian Linux, Fedora, Spectrum Copy Data Management and 21 more 2025-11-03 N/A 5.5 MEDIUM
A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large shared memory segment counts which could lead to resource exhaustion and DoS.
CVE-2020-10735 3 Fedoraproject, Python, Redhat 5 Fedora, Python, Enterprise Linux and 2 more 2025-11-03 N/A 7.5 HIGH
A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when using int("text"), a system could take 50ms to parse an int string with 100,000 digits and 5s for 1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not affected). The highest threat from this vulnerability is to system availability.
CVE-2024-7006 2 Libtiff, Redhat 5 Libtiff, Enterprise Linux, Enterprise Linux For Arm 64 and 2 more 2025-11-03 N/A 7.5 HIGH
A null pointer dereference flaw was found in Libtiff via `tif_dirinfo.c`. This issue may allow an attacker to trigger memory allocation failures through certain means, such as restricting the heap space size or injecting faults, causing a segmentation fault. This can cause an application crash, eventually leading to a denial of service.
CVE-2023-7250 2 Es, Redhat 5 Iperf3, Enterprise Linux, Enterprise Linux For Arm 64 and 2 more 2025-11-03 N/A 5.3 MEDIUM
A flaw was found in iperf, a utility for testing network performance using TCP, UDP, and SCTP. A malicious or malfunctioning client can send less than the expected amount of data to the iperf server, which can cause the server to hang indefinitely waiting for the remainder or until the connection gets closed. This will prevent other connections to the server, leading to a denial of service.
CVE-2023-3758 2 Fedoraproject, Redhat 23 Fedora, Sssd, Codeready Linux Builder and 20 more 2025-11-03 N/A 7.1 HIGH
A race condition flaw was found in sssd where the GPO policy is not consistently applied for authenticated users. This may lead to improper authorization issues, granting or denying access to resources inappropriately.
CVE-2023-3618 3 Debian, Libtiff, Redhat 3 Debian Linux, Libtiff, Enterprise Linux 2025-11-03 N/A 6.5 MEDIUM
A flaw was found in libtiff. A specially crafted tiff file can lead to a segmentation fault due to a buffer overflow in the Fax3Encode function in libtiff/tif_fax3.c, resulting in a denial of service.
CVE-2023-2283 3 Fedoraproject, Libssh, Redhat 3 Fedora, Libssh, Enterprise Linux 2025-11-03 N/A 6.5 MEDIUM
A vulnerability was found in libssh, where the authentication check of the connecting client can be bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen if there is insufficient memory or the memory usage is limited. The problem is caused by the return value `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK.
CVE-2022-2850 4 Debian, Fedoraproject, Port389 and 1 more 5 Debian Linux, Fedora, 389-ds-base and 2 more 2025-11-03 N/A 6.5 MEDIUM
A flaw was found In 389-ds-base. When the Content Synchronization plugin is enabled, an authenticated user can reach a NULL pointer dereference using a specially crafted query. This flaw allows an authenticated attacker to cause a denial of service. This CVE is assigned against an incomplete fix of CVE-2021-3514.
CVE-2022-0996 2 Fedoraproject, Redhat 3 Fedora, 389 Directory Server, Enterprise Linux 2025-11-03 4.0 MEDIUM 6.5 MEDIUM
A vulnerability was found in the 389 Directory Server that allows expired passwords to access the database to cause improper authentication.
CVE-2022-0918 2 Port389, Redhat 2 389-ds-base, Enterprise Linux 2025-11-03 5.0 MEDIUM 7.5 HIGH
A vulnerability was discovered in the 389 Directory Server that allows an unauthenticated attacker with network access to the LDAP port to cause a denial of service. The denial of service is triggered by a single message sent over a TCP connection, no bind or other authentication is required. The message triggers a segmentation fault that results in slapd crashing.
CVE-2021-3621 2 Fedoraproject, Redhat 8 Fedora, Sssd, Enterprise Linux and 5 more 2025-11-03 9.3 HIGH 8.8 HIGH
A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs-fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root access. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2025-6199 2 Gnome, Redhat 2 Gdkpixbuf, Enterprise Linux 2025-11-03 N/A 3.3 LOW
A flaw was found in the GIF parser of GdkPixbuf’s LZW decoder. When an invalid symbol is encountered during decompression, the decoder sets the reported output size to the full buffer length rather than the actual number of written bytes. This logic error results in uninitialized sections of the buffer being included in the output, potentially leaking arbitrary memory contents in the processed image.
