CVE-2023-38469 2 Avahi, Redhat 2 Avahi, Enterprise Linux 2025-11-03 N/A 6.2 MEDIUM
A vulnerability was found in Avahi, where a reachable assertion exists in avahi_dns_packet_append_record.
CVE-2023-2977 2 Opensc Project, Redhat 2 Opensc, Enterprise Linux 2025-11-03 N/A 7.1 HIGH
A vulnerbility was found in OpenSC. This security flaw cause a buffer overrun vulnerability in pkcs15 cardos_have_verifyrc_package. The attacker can supply a smart card package with malformed ASN1 context. The cardos_have_verifyrc_package function scans the ASN1 buffer for 2 tags, where remaining length is wrongly caculated due to moved starting pointer. This leads to possible heap-based buffer oob read. In cases where ASAN is enabled while compiling this causes a crash. Further info leak or more damage is possible.
CVE-2023-1981 3 Avahi, Fedoraproject, Redhat 3 Avahi, Fedora, Enterprise Linux 2025-11-03 N/A 5.5 MEDIUM
A vulnerability was found in the avahi library. This flaw allows an unprivileged user to make a dbus call, causing the avahi daemon to crash.
CVE-2022-4900 2 Php, Redhat 3 Php, Enterprise Linux, Software Collections 2025-11-03 N/A 6.2 MEDIUM
A vulnerability was found in PHP where setting the environment variable PHP_CLI_SERVER_WORKERS to a large value leads to a heap buffer overflow.
CVE-2022-3715 2 Gnu, Redhat 2 Bash, Enterprise Linux 2025-11-03 N/A 7.8 HIGH
A flaw was found in the bash package, where a heap-buffer overflow can occur in valid parameter_transform. This issue may lead to memory problems.
CVE-2022-0934 2 Redhat, Thekelleys 2 Enterprise Linux, Dnsmasq 2025-11-03 N/A 7.5 HIGH
A single-byte, non-arbitrary write/use-after-free flaw was found in dnsmasq. This flaw allows an attacker who sends a crafted packet processed by dnsmasq, potentially causing a denial of service.
CVE-2021-4189 4 Debian, Netapp, Python and 1 more 5 Debian Linux, Ontap Select Deploy Administration Utility, Python and 2 more 2025-11-03 N/A 5.3 MEDIUM
A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV (passive) mode. The issue is how the FTP client trusts the host from the PASV response by default. This flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which otherwise would not have been possible.
CVE-2021-42781 3 Fedoraproject, Opensc Project, Redhat 3 Fedora, Opensc, Enterprise Linux 2025-11-03 5.0 MEDIUM 5.3 MEDIUM
Heap buffer overflow issues were found in Opensc before version 0.22.0 in pkcs15-oberthur.c that could potentially crash programs using the library.
CVE-2021-42780 3 Fedoraproject, Opensc Project, Redhat 3 Fedora, Opensc, Enterprise Linux 2025-11-03 5.0 MEDIUM 5.3 MEDIUM
A use after return issue was found in Opensc before version 0.22.0 in insert_pin function that could potentially crash programs using the library.
CVE-2021-42779 3 Fedoraproject, Opensc Project, Redhat 3 Fedora, Opensc, Enterprise Linux 2025-11-03 5.0 MEDIUM 5.3 MEDIUM
A heap use after free issue was found in Opensc before version 0.22.0 in sc_file_valid.
CVE-2021-42778 3 Fedoraproject, Opensc Project, Redhat 3 Fedora, Opensc, Enterprise Linux 2025-11-03 5.0 MEDIUM 5.3 MEDIUM
A heap double free issue was found in Opensc before version 0.22.0 in sc_pkcs15_free_tokeninfo.
CVE-2021-3737 6 Canonical, Fedoraproject, Netapp and 3 more 17 Ubuntu Linux, Fedora, Hci and 14 more 2025-11-03 7.1 HIGH 7.5 HIGH
A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability.
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-2021-3426 6 Debian, Fedoraproject, Netapp and 3 more 10 Debian Linux, Fedora, Cloud Backup and 7 more 2025-11-03 2.7 LOW 5.7 MEDIUM
There's a flaw in Python 3's pydoc. A local or adjacent attacker who discovers or is able to convince another local or adjacent user to start a pydoc server could access the server and use it to disclose sensitive information belonging to the other user that they would not normally be able to access. The highest risk of this flaw is to data confidentiality. This flaw affects Python versions before 3.8.9, Python versions before 3.9.3 and Python versions before 3.10.0a7.
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-2023-52356 2 Libtiff, Redhat 2 Libtiff, Enterprise Linux 2025-11-03 N/A 7.5 HIGH
A segment fault (SEGV) flaw was found in libtiff that could be triggered by passing a crafted tiff file to the TIFFReadRGBATileExt() API. This flaw allows a remote attacker to cause a heap-buffer overflow, 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.
