CVE-2026-96641

A flaw was found in Pillow. When processing text dimensions with certain fonts, negative character spacing values are not properly validated during text-width calculation, causing an integer overflow. A remote attacker could exploit this vulnerability by providing crafted text or font data to an...

PYSEC-2026-4340

Pillow is a Python imaging library. Prior to 13.0.0, PILfont text-width accumulation in src/imaging.c checks positive glyph advances against INTMAX but does not check negative advances against INTMIN. Repeating a signed 16-bit advance of -32768 can therefore execute a signed C integer overflow in...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the textwidth function in src/imaging.c, where accumulating negative glyph advance widths can cause the integer accumulator xsize to wrap below INTMIN. An attacker can trigger this by supplying text...

CVE-2026-96641

The Pillow Python imaging library is vulnerable to a signed C integer overflow in src/_imaging.c prior to version 13.0.0 . The PILfont text-width accumulation logic fails to check negative glyph advances against INT_MIN, allowing repeated 16-bit advances of -32768 to result in a large positive wi...

golang: cmd/compile: possible memory corruption after bound check elimination

A flaw was found in the cmd/compile package in the Go standard library. The compiler fails to correctly check for integer overflow or underflow in arithmetic operations involving loop induction variables. As a result, the compiler allows invalid memory indexing to occur at runtime, potentially...

Critical GitLab Flaw (CVSS 10.0) Could Allow Unauthenticated RCE Across 12 Years of Releases

GitLab released fixes on October 21 for a flaw that lets an attacker run code on a self-managed server without logging in, and it affects every version of the software going back to 7.0, released in 2014. The fix matters even for administrators who patched nine days earlier: the October 12 update...

CVE-2026-98634

A flaw was found in the Linux kernel's SCSI ZBC Zoned Block Commands driver. This vulnerability can lead to a denial of service DoS when the system attempts to scan a storage device that reports an excessively large number of zones. Due to integer truncation and overflow during zone calculations,...

SUSE CVE-2026-91189

The GUIX binary resource loader never checks that a font page's glyph range is well formed. gxpageheaderfirstglyph and gxpageheaderlastglyph are read verbatim from the file and only the upper bound of lastglyph is validated, so a page declaring firstglyph lastglyph makes last - first + 1 underflo...

SUSE CVE-2026-114045

FreeRDP before 3.32.1 contains a heap-based buffer overflow in the server-side rdpsnd channel because an integer wraparound in rdpsndserverselectformat DVIADPCM block-alignment arithmetic bypasses validation. A malicious RDP client can send two SNDCFORMATS PDUs with an nBlockAlign too small for...

CVE-2026-102699

A flaw was found in Xen. A malicious guest domain can trigger an integer underflow when requesting cache flush operations. This calculation error leads to an excessively long processing loop in the hypervisor, causing the host system to crash and resulting in a Denial of Service DoS. Mitigation...
