CVE-2025-43718	Oct 01, 2025	Poppler 24.06.1-25.03: SEGV via deep metadata recursion (GTS_PDFEVersion) Poppler 24.06.1 through 25.x before 25.04.0 allows stack consumption and a SIGSEGV via deeply nested structures within the metadata (such as GTS_PDFEVersion) of a PDF document, e.g., a regular expression for a long pdfsubver string. This occurs in Dict::lookup, Catalog::getMetadata, and associated functions in PDFDoc, with deep recursion in the regex executor (std::__detail::_Executor).	Poppler
CVE-2025-50420	Aug 04, 2025	Poppler v25.04.0 pdfseparate DoS via Infinite Recursion An issue in the pdfseparate utility of freedesktop poppler v25.04.0 allows attackers to cause an infinite recursion via supplying a crafted PDF file. This can lead to a Denial of Service (DoS).	Poppler
CVE-2025-52968	Jun 23, 2025	CVE-2025-52968: xdg-utils <=1.2.1 xdg-open CSRF via SameSite=Strict xdg-open in xdg-utils through 1.2.1 can send requests containing SameSite=Strict cookies, which can facilitate CSRF. (For example, xdg-open could be modified to, by default, associate x-scheme-handler/https with the execution of a browser with command-line options that arrange for an empty cookie store, although this would add substantial complexity, and would not be considered a desirable or expected behavior by all users.) NOTE: this is disputed because integrations of xdg-open typically do not provide information about whether the xdg-open command and arguments were manually entered by a user, or whether they were the result of a navigation from content in an untrusted origin.	Xdg Utils

CVE-2020-35702	Dec 25, 2020	DCTStream::getChars in DCTStream.cc in Poppler 20.12.1 has a heap-based buffer overflow via a crafted PDF document DCTStream::getChars in DCTStream.cc in Poppler 20.12.1 has a heap-based buffer overflow via a crafted PDF document. NOTE: later reports indicate that this only affects builds from Poppler git clones in late December 2020, not the 20.12.1 release. In this situation, it should NOT be considered a Poppler vulnerability. However, several third-party Open Source projects directly rely on Poppler git clones made at arbitrary times, and therefore the CVE remains useful to users of those projects	Poppler

CVE-2019-12749	Jun 11, 2019	dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon) dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass.	Dbus
