Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick, specifically in the MagickCore/statistic.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. This likely leads to a disruption in t...

Astra Linux – Vulnerability in imagemagick

An integer overflow issue was discovered in ImageMagick’s ExportIndexQuantum function in MagickCore/quantum-export.c. Function calls to GetPixelIndex could result in values that are outside the representable range for ‘unsigned char’. When ImageMagick processes a specially crafted PDF file, this...

A flaw was discovered in ImageMagick within MagickCore/statistic.c. An attacker who submits a crafted file processed by ImageMagick could induce undefined behavior, resulting in an excessively large value for the 64-bit type ssizet. This likely leads to a disruption in the application’s...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Wifi: Radiotap: Reject Radiotap with unknown bits The Radiotap parser is currently only used with the radiotap namespace not with vendor namespaces. However, if the undefined field 18 is used, the alignment/size of the data is al...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: net: mdio: fixed an undefined behavior in bit shifting for mdiobusregister. Shifting a signed 32-bit value by 31 bits is undefined; therefore, the significant bit was changed to unsigned. The UBSAN warning appears as follows:...

Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick’s MagickCore/statistic.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 type unsigned long. This likely affects the availability of the application, but ...

Astra Linux – Vulnerability in ffmpeg5

It was discovered that FFmpeg version n6.1 contains a heap buffer overflow vulnerability in the drawblockrectangle function of libavfilter/vfcodecview.c. This vulnerability allows attackers to cause undefined behavior or a Denial of Service DoS attack through crafted inputs...

Astra Linux – Vulnerability in imagemagick

A floating-point mathematical calculation within the ScaleAnyToQuantum function in /MagickCore/quantum-private.h could lead to undefined behavior, resulting in a value that falls outside the range of the type unsigned long long. This flaw can be triggered by a malicious input file under certain...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerabilities have been resolved: media: gspca: cpia1: shift-out-of-bounds in setflicker Syzkaller reported the following issue: UBSAN: Shift-out-of-bounds in drivers/media/usb/gspca/cpia1.c:1031:27; shift exponent 245 is too large for a 32-bit type ‘int’. Whe...

Astra Linux – Vulnerability in imagemagick

In ImageMagick, there are many cases where the alignment of the double type is incorrect. The double type requires 8 bytes of alignment, while the float type requires 4 bytes of alignment. This issue is addressed in the MagickCore/property.c file. Whenever malicious or untrusted input is processe...

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

In the Linux kernel, the following vulnerability has been resolved: media: uvcvideo: Skipping the parsing of frames of type UVCVSUNDEFINED in uvcparseformat. This issue can lead to out-of-bounds write attacks, as frames of this type were not taken into consideration when calculating the size of t...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Make ICCSGIEL1 undef in the absence of a vGICv3 On a system with a GICv3, if a guest has not been configured with a GICv3, and the host is not capable of emulating GICv2, writing to any of the ICCSGIEL1 registers will...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: nfc: nci: assert requested protocol is valid The protocol is used in a bit mask to determine whether the protocol is supported. It is asserted that the provided protocol is less than the maximum value defined, thereby avoiding...

In the Linux kernel, the following vulnerabilities have been resolved: netfilter: nfconntrackh323: Added protection against bmp length being out of range. The UBSAN load reports an exception due to bitwise shifts that are out of bounds for their data type. vmlinux getbitmapb=75 + 712 vmlinux...

Astra Linux – Vulnerability in Firefox, 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 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...
