CVE-2023-34969 3 Debian, Fedoraproject, Freedesktop 3 Debian Linux, Fedora, Dbus 2025-06-09 N/A 6.5 MEDIUM
D-Bus before 1.15.6 sometimes allows unprivileged users to crash dbus-daemon. If a privileged user with control over the dbus-daemon is using the org.freedesktop.DBus.Monitoring interface to monitor message bus traffic, then an unprivileged user with the ability to connect to the same dbus-daemon can cause a dbus-daemon crash under some circumstances via an unreplyable message. When done on the well-known system bus, this is a denial-of-service vulnerability. The fixed versions are 1.12.28, 1.14.8, and 1.15.6.
CVE-2023-27538 6 Broadcom, Debian, Fedoraproject and 3 more 15 Brocade Fabric Operating System Firmware, Debian Linux, Fedora and 12 more 2025-06-09 N/A 5.5 MEDIUM
An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously established SSH connection despite the fact that an SSH option was modified, which should have prevented reuse. libcurl maintains a pool of previously used connections to reuse them for subsequent transfers if the configurations match. However, two SSH settings were omitted from the configuration check, allowing them to match easily, potentially leading to the reuse of an inappropriate connection.
CVE-2023-27535 5 Debian, Fedoraproject, Haxx and 2 more 14 Debian Linux, Fedora, Libcurl and 11 more 2025-06-09 N/A 5.9 MEDIUM
An authentication bypass vulnerability exists in libcurl <8.0.0 in the FTP connection reuse feature that can result in wrong credentials being used during subsequent transfers. Previously created connections are kept in a connection pool for reuse if they match the current setup. However, certain FTP settings such as CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC, and CURLOPT_USE_SSL were not included in the configuration match checks, causing them to match too easily. This could lead to libcurl using the wrong credentials when performing a transfer, potentially allowing unauthorized access to sensitive information.
CVE-2022-29458 3 Apple, Debian, Gnu 3 Macos, Debian Linux, Ncurses 2025-06-09 5.8 MEDIUM 7.1 HIGH
ncurses 6.3 before patch 20220416 has an out-of-bounds read and segmentation violation in convert_strings in tinfo/read_entry.c in the terminfo library.
CVE-2022-1271 4 Debian, Gnu, Redhat and 1 more 4 Debian Linux, Gzip, Jboss Data Grid and 1 more 2025-06-09 N/A 8.8 HIGH
An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system.
CVE-2021-27645 3 Debian, Fedoraproject, Gnu 3 Debian Linux, Fedora, Glibc 2025-06-09 1.9 LOW 2.5 LOW
The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system. This is related to netgroupcache.c.
CVE-2021-22945 8 Apple, Debian, Fedoraproject and 5 more 25 Macos, Debian Linux, Fedora and 22 more 2025-06-09 5.8 MEDIUM 9.1 CRITICAL
When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*.
CVE-2021-22924 7 Debian, Fedoraproject, Haxx and 4 more 53 Debian Linux, Fedora, Libcurl and 50 more 2025-06-09 4.3 MEDIUM 3.7 LOW
libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert' into account and it compared the involved paths *case insensitively*,which could lead to libcurl reusing wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can setto qualify how to verify the server certificate.
CVE-2021-22890 8 Broadcom, Debian, Fedoraproject and 5 more 11 Fabric Operating System, Debian Linux, Fedora and 8 more 2025-06-09 4.3 MEDIUM 3.7 LOW
curl 7.63.0 to and including 7.75.0 includes vulnerability that allows a malicious HTTPS proxy to MITM a connection due to bad handling of TLS 1.3 session tickets. When using a HTTPS proxy and TLS 1.3, libcurl can confuse session tickets arriving from the HTTPS proxy but work as if they arrived from the remote server and then wrongly "short-cut" the host handshake. When confusing the tickets, a HTTPS proxy can trick libcurl to use the wrong session ticket resume for the host and thereby circumvent the server TLS certificate check and make a MITM attack to be possible to perform unnoticed. Note that such a malicious HTTPS proxy needs to provide a certificate that curl will accept for the MITMed server for an attack to work - unless curl has been told to ignore the server certificate check.
CVE-2021-22876 8 Broadcom, Debian, Fedoraproject and 5 more 12 Fabric Operating System, Debian Linux, Fedora and 9 more 2025-06-09 5.0 MEDIUM 5.3 MEDIUM
curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request.
CVE-2024-0753 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2025-06-07 N/A 6.5 MEDIUM
In specific HSTS configurations an attacker could have bypassed HSTS on a subdomain. This vulnerability affects Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7.
CVE-2025-3891 3 Apache, Debian, Redhat 3 Http Server, Debian Linux, Enterprise Linux 2025-06-06 N/A 7.5 HIGH
A flaw was found in the mod_auth_openidc module for Apache httpd. This flaw allows a remote, unauthenticated attacker to trigger a denial of service by sending an empty POST request when the OIDCPreservePost directive is enabled. The server crashes consistently, affecting availability.
CVE-2023-6347 3 Debian, Fedoraproject, Google 3 Debian Linux, Fedora, Chrome 2025-06-05 N/A 8.8 HIGH
Use after free in Mojo in Google Chrome prior to 119.0.6045.199 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
CVE-2024-31309 3 Apache, Debian, Fedoraproject 3 Traffic Server, Debian Linux, Fedora 2025-06-03 N/A 7.5 HIGH
HTTP/2 CONTINUATION DoS attack can cause Apache Traffic Server to consume more resources on the server.  Version from 8.0.0 through 8.1.9, from 9.0.0 through 9.2.3 are affected. Users can set a new setting (proxy.config.http2.max_continuation_frames_per_minute) to limit the number of CONTINUATION frames per minute.  ATS does have a fixed amount of memory a request can use and ATS adheres to these limits in previous releases. Users are recommended to upgrade to versions 8.1.10 or 9.2.4 which fixes the issue.
CVE-2023-46838 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2025-06-02 N/A 7.5 HIGH
Transmit requests in Xen's virtual network protocol can consist of multiple parts. While not really useful, except for the initial part any of them may be of zero length, i.e. carry no data at all. Besides a certain initial portion of the to be transferred data, these parts are directly translated into what Linux calls SKB fragments. Such converted request parts can, when for a particular SKB they are all of length zero, lead to a de-reference of NULL in core networking code.
CVE-2025-26465 4 Debian, Netapp, Openbsd and 1 more 6 Debian Linux, Active Iq Unified Manager, Ontap and 3 more 2025-06-02 N/A 6.8 MEDIUM
A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high.
CVE-2023-28484 2 Debian, Xmlsoft 2 Debian Linux, Libxml2 2025-05-30 N/A 6.5 MEDIUM
In libxml2 before 2.10.4, parsing of certain invalid XSD schemas can lead to a NULL pointer dereference and subsequently a segfault. This occurs in xmlSchemaFixupComplexType in xmlschemas.c.
CVE-2022-43680 4 Debian, Fedoraproject, Libexpat Project and 1 more 18 Debian Linux, Fedora, Libexpat and 15 more 2025-05-30 N/A 7.5 HIGH
In libexpat through 2.4.9, there is a use-after free caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate in out-of-memory situations.
CVE-2022-40674 3 Debian, Fedoraproject, Libexpat Project 3 Debian Linux, Fedora, Libexpat 2025-05-30 N/A 8.1 HIGH
libexpat before 2.4.9 has a use-after-free in the doContent function in xmlparse.c.
CVE-2022-37434 6 Apple, Debian, Fedoraproject and 3 more 21 Ipados, Iphone Os, Macos and 18 more 2025-05-30 N/A 9.8 CRITICAL
zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference).
