CVE-2023-5992 2 Opensc Project, Redhat 11 Opensc, Enterprise Linux, Enterprise Linux Eus and 8 more 2025-11-03 N/A 5.6 MEDIUM
A vulnerability was found in OpenSC where PKCS#1 encryption padding removal is not implemented as side-channel resistant. This issue may result in the potential leak of private data.
CVE-2023-40661 2 Opensc Project, Redhat 2 Opensc, Enterprise Linux 2025-11-03 N/A 5.4 MEDIUM
Several memory vulnerabilities were identified within the OpenSC packages, particularly in the card enrollment process using pkcs15-init when a user or administrator enrolls cards. To take advantage of these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB device or smart card to manipulate responses to APDUs. This manipulation can potentially allow compromise key generation, certificate loading, and other card management operations during enrollment.
CVE-2023-40660 2 Opensc Project, Redhat 2 Opensc, Enterprise Linux 2025-11-03 N/A 6.6 MEDIUM
A flaw was found in OpenSC packages that allow a potential PIN bypass. When a token/card is authenticated by one process, it can perform cryptographic operations in other processes when an empty zero-length pin is passed. This issue poses a security risk, particularly for OS logon/screen unlock and for small, permanently connected tokens to computers. Additionally, the token can internally track login status. This flaw allows an attacker to gain unauthorized access, carry out malicious actions, or compromise the system without the user's awareness.
CVE-2023-38473 2 Avahi, Redhat 2 Avahi, Enterprise Linux 2025-11-03 N/A 6.2 MEDIUM
A vulnerability was found in Avahi. A reachable assertion exists in the avahi_alternative_host_name() function.
CVE-2023-38472 2 Avahi, Redhat 2 Avahi, Enterprise Linux 2025-11-03 N/A 6.2 MEDIUM
A vulnerability was found in Avahi. A reachable assertion exists in the avahi_rdata_parse() function.
CVE-2023-38471 2 Avahi, Redhat 2 Avahi, Enterprise Linux 2025-11-03 N/A 6.2 MEDIUM
A vulnerability was found in Avahi. A reachable assertion exists in the dbus_set_host_name function.
CVE-2023-38470 2 Avahi, Redhat 2 Avahi, Enterprise Linux 2025-11-03 N/A 6.2 MEDIUM
A vulnerability was found in Avahi. A reachable assertion exists in the avahi_escape_label() function.
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.
