Astra Linux – Vulnerability in glibc

Calling getnetbyaddr or getnetbyaddrr with a configured nsswitch.conf that specifies the library’s DNS backend can lead to a situation where a zero-valued network is queried during operations in the GNU C Library versions 2.0 to 2.42. This could result in the leakage of stack contents to the...

Astra Linux – Vulnerability in underscore

Underscore.js is a utility-belt library for JavaScript. Prior to version 1.13.8, the .flatten and .isEqual functions used recursion without a depth limit. Under very specific conditions, an attacker could exploit this in a Denial of Service DoS attack by triggering a stack overflow. Untrusted...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, there was a stack buffer overflow vulnerability in the MNG encoder. There were missing bounds checks, which could allow the stack to be corrupted by...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Staging: rtl8723bs: Fixed a stack buffer overflow issue during the parsing of the OnAssocReq IE. The length of the Supported Rates IE from an incoming Association Request frame was directly used as the length for the memcpy...

Astra Linux – Vulnerability in Capstone

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and earlier, a unchecked return from vsnprintf in SStreamconcat allowed a malicious csoptmem.vsnprintf to manipulate SStream’s index beyond its limit, resulting in a stack buffer underflow/overflow when the next write operation occurre...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fixed the kernel stack leak in irdmacreateuserah. struct irdmacreateahresp // 8 bytes, no padding u32 ahid; // Offset 0 – SET uresp.ahid = ah-scah.ahinfo.ahidx u8 rsvd4; // Offset 4 – NEVER SET - LEAK ; The rsvd4 fiel...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: scs: A wrong parameter was fixed in scsmagic. The scsmagic function requires a void variable, but a struct taskstruct is provided instead. taskscstsk represents the starting address of the task’s shadow call stack, and...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: bpf: A stack-out-of-bounds write occurred in devmap. The getupperifindexes function iterates over all upper devices and writes their indices into an array without checking bounds. As a result, callers may assume that the maximum...

postgresql: PostgreSQL: Arbitrary code execution vulnerability in 'refint' module

A flaw was found in PostgreSQL. A stack buffer overflow in the 'refint' module allows an unprivileged database user to execute arbitrary code as the operating system user running the database. Additionally, a separate vulnerability exists where, if an application uses a user-controlled column as ...

CVE-2026-42450 OpenColorIO vulnerable to stack buffer overflow via unbounded `sscanf %s` in Spi3D (.spi3d) LUT parser

OpenColorIO is a color management framework for visual effects and animation. Prior to version 2.5.2, FileFormatSpi3D.cpp:163 uses sscanf with %s into 64-byte stack buffers when parsing LUT data lines. Input comes from lineBuffer4096, so a crafted .spi3d file can overflow by 4000 bytes on...

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...

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...
