CVE-2026-5947

Undefined behavior may result due to a race condition leading to a use-after-free violation. If BIND receives an incoming DNS message signed with SIG0, it begins work to validate that signature. If, during that validation, the "recursive-clients" limit is reached as would occur during a query...

CVE-2026-5947

CVE-2026-5947 describes an undefined behavior due to a race condition in SIG(0) validation during DNS message processing under load. Affected are BIND 9.20.0–9.20.22, 9.21.0–9.21.21, and 9.20.9-S1–9.20.22-S1; versions 9.18.28–9.18.49 and 9.18.28-S1–9.18.49-S1 are not affected. Under a query flood...

Astra Linux – Vulnerability in Firefox and Thunderbird

The ShutdownObserver function was susceptible to potentially undefined behavior due to its reliance on a dynamic type that lacked a virtual destructor. This vulnerability affects Firefox ESR 115.6, Thunderbird 115.6, and Firefox 121...

Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick within MagickCore/quantum.h. An attacker who submits a crafted file processed by ImageMagick could induce undefined behavior, resulting in values that are outside the range of type unsigned char. This likely application availability issues, but it may also cau...

Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick within MagickCore/quantum.h. An attacker who submits a crafted file processed by ImageMagick could induce undefined behavior, resulting in values that fall outside the range of types float and unsigned char. This likely leads to a disruption in the application...

Astra Linux – Vulnerability in imagemagick

The function WritePALMImage in /coders/palm.c uses sizet type conversions in several parts of the calculation. This could lead to values that are outside the range of the representable type unsigned long, resulting in undefined behavior when a malicious input file is processed by ImageMagick...

Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick in the coders/txt.c file. An attacker who submits a crafted file processed by ImageMagick could trigger undefined behavior, resulting in values that are outside the range of the type unsigned long long. This likely leads to a disruption in the application’s...

Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick, specifically in the file MagickCore/quantum-export.c. An attacker who submits a crafted file processed by ImageMagick could trigger undefined behavior, resulting in values that are outside the range of the unsigned long long type, as well as a shift exponent...

Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick in versions prior to 7.0.11 and prior to 6.9.12. In these versions, a division by zero in the WaveImage function of MagickCore/visual-effects.c could lead to undefined behavior when a malicious image file was submitted to an application that used ImageMagick...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: net: stmmac: fixed an issue with left shift overflow in DMA queues When the queue number is greater than 4, left shift overflows due to the 32-bit integer variable used in calculations. The mask calculation for MTLRXQDMAMAP1 i...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: ALSA: firewire-lib: fixed an uninitialized flag for AV/C deferred transactions. AV/C deferred transactions were supported at commit 00a7bb81c20f “ALSA: firewire-lib: add support for deferred transactions”. However, the ‘deferrabl...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU implementation of VMWare’s paravirtual RDMA device in versions prior to 6.1.0. The issue occurs when handling a “PVRDMAREGDSRHIGH” write from the guest, and it may result in a crash of QEMU or cause undefined behavior due to the access of an uninitialized pointer...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: ena: Fixed an out-of-bounds shift in the exponential backoff mechanism. The ENA adapters on our instances occasionally reset. Recently, a UBSAN failure was logged on the console during this process: UBSAN: Out-of-bounds shif...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: lib/fonts: Fixed undefined behavior in bit shifting for getdefaultfont. Shifting a signed 32-bit value by 31 bits is undefined; therefore, the significant bit was changed to unsigned. The UBSAN warning “calltrace” is as follow...

Astra Linux – Vulnerability in imagemagick

In the functions CatromWeights, MeshInterpolate, InterpolatePixelChannel, InterpolatePixelChannels, and InterpolatePixelInfo, which are all part of /MagickCore/pixel.c, there were multiple unconstrained pixel offset calculations that were used with the floor function. These calculations resulted ...
