UBUNTU-CVE-2026-6694

A flaw was found in GIMP's file-png plugin. A remote attacker can exploit this by crafting a malicious Animated Portable Network Graphics APNG image containing an oversized tRNS chunk. This can lead to a stack-based buffer overflow CWE-121, causing the file-png plugin to crash and resulting in a...

CVE-2026-18588

The CVE-2026-18588 affects the Wavlink WL-NU516U1 (708c073-mt7628) device, with a stack-based buffer overflow in nas.cgi caused by manipulation of CONTENT_LENGTH. This allows remote exploitation and could impact confidentiality, integrity, and availability. A fixed version has been released by th...

postgresql: PostgreSQL libpq: Buffer overflow allows server superuser to overwrite client stack memory

A flaw was found in PostgreSQL libpq. A server superuser can exploit a buffer overflow vulnerability in the PQfn function, which is used by client functions such as loexport, loread, lolseek64, and lotell64. This allows the superuser to send an arbitrarily large response, overwriting the client's...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in XKB key types due to unchecked shift levels

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel XkbNumKbdGroups but CheckKeyTypes does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in font alias resolution due to libXfont2 name length mismatch

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in XKB SetMap request via mapWidths indexing

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. XkbSetMapChecks declares a fixed-size stack buffer mapWidths256 indexed by key type index. The helper function CheckKeyTypes writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This...

gstreamer: GStreamer: Arbitrary code execution via stack-based buffer overflow in qtdemux

A stack-based buffer overflow in GStreamer's qtdemux component allows attackers to execute arbitrary code via specially crafted input. This occurs due to insufficient data length validation when parsing UncompressedFrameConfigBox structures...
