postgresql: PostgreSQL: Stack buffer overflow via OUT parameter count manipulation

A flaw was found in PostgreSQL. An object creator can exploit a stack buffer overflow vulnerability within the argument name matching component. By manipulating the OUT parameter count, an attacker can write limited arbitrary bytes 0x0 and 0x1 to server memory, which may lead to unknown impacts...

CVE-2026-63276 Stack buffer overflow in CFF to Type 1 font conversion

LibreOffice converts CFF fonts to Type 1 when it subsets a font, which happens when a document is exported to PDF, and CFF fonts may be embedded in documents. A stack buffer overflow existed in that conversion. The converted operators were written into a fixed size buffer with no check that they...

CVE-2026-63276

CVE-2026-63276 is a stack buffer overflow in LibreOffice 's CFF-to-Type 1 font conversion, which occurs when the application subsets fonts during PDF export. A glyph that emits many operators writes past the end of a fixed-size buffer with no bounds check. In fixed versions, remaining capacity is...

EUVD-2026-84355

LibreOffice can read CFF fonts, which may be embedded in documents. A stack buffer overflow existed when reading the hints of a glyph. The number of hints was checked against the wrong bound, so a glyph declaring more hints than the array can hold wrote past its end. In fixed versions the hint...

CVE-2026-63275 Stack buffer overflow in CFF font hint handling

LibreOffice can read CFF fonts, which may be embedded in documents. A stack buffer overflow existed when reading the hints of a glyph. The number of hints was checked against the wrong bound, so a glyph declaring more hints than the array can hold wrote past its end. In fixed versions the hint...

CVE-2026-63275

LibreOffice is vulnerable to a stack buffer overflow when processing CFF fonts embedded in documents. The root cause is a bounds-checking error: the number of glyph hints was validated against the wrong limit, allowing a crafted glyph to declare more hints than the stack array could hold and writ...

encoding/xml: golang: Go: Denial of Service via XML decoding recursion depth issue

A flaw was found in the encoding/xml package of Go. The DecodeElement function failed to correctly track recursion depth, which could lead to stack exhaustion. A remote attacker could exploit this vulnerability by providing a specially crafted XML input, resulting in a Denial of Service DoS for t...

kernel: netfilter: conntrack: remove sprintf usage

A flaw was found in the Linux kernel's netfilter conntrack module. This vulnerability arises from the use of sprintf and insufficient buffer sizing in the manglecontentlen function, which can lead to a stack-out-of-bounds write. An attacker could potentially exploit this memory corruption issue t...
