| CVE-2025-26598 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2025-05-13 | 7.8 High |
| An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice() searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching device ID is found, which can lead to out-of-bounds memory access. | ||||
| CVE-2025-26597 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2025-05-13 | 7.8 High |
| A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey() is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because the key actions are of the wrong size. | ||||
| CVE-2025-26596 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2025-05-13 | 7.8 High |
| A heap overflow flaw was found in X.Org and Xwayland. The computation of the length in XkbSizeKeySyms() differs from what is written in XkbWriteKeySyms(), which may lead to a heap-based buffer overflow. | ||||
| CVE-2025-26594 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2025-05-13 | 7.8 High |
| A use-after-free flaw was found in X.Org and Xwayland. The root cursor is referenced in the X server as a global variable. If a client frees the root cursor, the internal reference points to freed memory and causes a use-after-free. | ||||
| CVE-2024-9632 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2025-05-13 | 7.8 High |
| A flaw was found in the X.org server. Due to improperly tracked allocation size in _XkbSetCompatMap, a local attacker may be able to trigger a buffer overflow condition via a specially crafted payload, leading to denial of service or local privilege escalation in distributions where the X.org server is run with root privileges. | ||||
| CVE-2023-50868 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2025-05-12 | 7.5 High |
| The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped) allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC responses in a random subdomain attack, aka the "NSEC3" issue. The RFC 5155 specification implies that an algorithm must perform thousands of iterations of a hash function in certain situations. | ||||
| CVE-2023-50387 | 8 Fedoraproject, Isc, Microsoft and 5 more | 18 Fedora, Bind, Windows Server 2008 and 15 more | 2025-05-12 | 7.5 High |
| Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records. | ||||
| CVE-2025-4083 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2025-05-09 | 9.1 Critical |
| A process isolation vulnerability in Thunderbird stemmed from improper handling of javascript: URIs, which could allow content to execute in the top-level document's process instead of the intended frame, potentially enabling a sandbox escape. This vulnerability affects Firefox < 138, Firefox ESR < 128.10, Firefox ESR < 115.23, Thunderbird < 138, and Thunderbird < 128.10. | ||||
| CVE-2025-4087 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2025-05-09 | 6.5 Medium |
| A vulnerability was identified in Thunderbird where XPath parsing could trigger undefined behavior due to missing null checks during attribute access. This could lead to out-of-bounds read access and potentially, memory corruption. This vulnerability affects Firefox < 138, Firefox ESR < 128.10, Thunderbird < 138, and Thunderbird < 128.10. | ||||
| CVE-2025-4091 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2025-05-09 | 6.5 Medium |
| Memory safety bugs present in Firefox 137, Thunderbird 137, Firefox ESR 128.9, and Thunderbird 128.9. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 138, Firefox ESR < 128.10, Thunderbird < 138, and Thunderbird < 128.10. | ||||
| CVE-2025-4093 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2025-05-09 | 6.5 Medium |
| Memory safety bug present in Firefox ESR 128.9, and Thunderbird 128.9. This bug showed evidence of memory corruption and we presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 128.10 and Thunderbird < 128.10. | ||||
| CVE-2025-27363 | 3 Debian, Freetype, Redhat | 9 Debian Linux, Freetype, Enterprise Linux and 6 more | 2025-05-07 | 8.1 High |
| An out of bounds write exists in FreeType versions 2.13.0 and below (newer versions of FreeType are not vulnerable) when attempting to parse font subglyph structures related to TrueType GX and variable font files. The vulnerable code assigns a signed short value to an unsigned long and then adds a static value causing it to wrap around and allocate too small of a heap buffer. The code then writes up to 6 signed long integers out of bounds relative to this buffer. This may result in arbitrary code execution. This vulnerability may have been exploited in the wild. | ||||
| CVE-2018-25032 | 12 Apple, Azul, Debian and 9 more | 46 Mac Os X, Macos, Zulu and 43 more | 2025-05-06 | 7.5 High |
| zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. | ||||
| CVE-2017-5715 | 8 Arm, Canonical, Debian and 5 more | 230 Cortex-a, Ubuntu Linux, Debian Linux and 227 more | 2025-05-06 | 5.6 Medium |
| Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. | ||||
| CVE-2022-25315 | 6 Debian, Fedoraproject, Libexpat Project and 3 more | 12 Debian Linux, Fedora, Libexpat and 9 more | 2025-05-05 | 9.8 Critical |
| In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. | ||||
| CVE-2022-25236 | 5 Debian, Libexpat Project, Oracle and 2 more | 11 Debian Linux, Libexpat, Http Server and 8 more | 2025-05-05 | 9.8 Critical |
| xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters into namespace URIs. | ||||
| CVE-2022-25235 | 6 Debian, Fedoraproject, Libexpat Project and 3 more | 12 Debian Linux, Fedora, Libexpat and 9 more | 2025-05-05 | 9.8 Critical |
| xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks for whether a UTF-8 character is valid in a certain context. | ||||
| CVE-2023-0767 | 2 Mozilla, Redhat | 10 Firefox, Firefox Esr, Thunderbird and 7 more | 2025-05-05 | 8.8 High |
| An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory writes via PKCS 12 Safe Bag attributes being mishandled. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8. | ||||
| CVE-2024-50302 | 2 Linux, Redhat | 9 Linux Kernel, Enterprise Linux, Openshift and 6 more | 2025-05-04 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: HID: core: zero-initialize the report buffer Since the report buffer is used by all kinds of drivers in various ways, let's zero-initialize it during allocation to make sure that it can't be ever used to leak kernel memory via specially-crafted report. | ||||
| CVE-2024-53141 | 2 Linux, Redhat | 8 Linux Kernel, Enterprise Linux, Rhel Aus and 5 more | 2025-05-04 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: add missing range check in bitmap_ip_uadt When tb[IPSET_ATTR_IP_TO] is not present but tb[IPSET_ATTR_CIDR] exists, the values of ip and ip_to are slightly swapped. Therefore, the range check for ip should be done later, but this part is missing and it seems that the vulnerability occurs. So we should add missing range checks and remove unnecessary range checks. | ||||
