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 32-bit unsigned integer overflow in the XWD X Windows encoder, which could lead to an undersized heap buffer allocation. When writing an extremely...

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, the MAT decoder used 32-bit arithmetic due to incorrect parenthesization, resulting in a heap over-read. This vulnerability has been fixed in versions 7.1.2-16...

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 heap-buffer-overflow vulnerability in the PCL encoding process, due to an undersized output buffer allocation. This vulnerability has been fixed in...

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 heap-use-after-free vulnerability in the MSL encoder, where a cloned image was destroyed twice. The MSL encoder does not support writing MSL, so the...

Astra Linux – Vulnerability in libpng1.6

LIBPNG is a reference library used in applications that read, create, and manipulate PNG Portable Network Graphics raster image files. In versions 1.6.36 through 1.6.55, there was an out-of-bounds read and write vulnerability in libpng’s ARM/AArch64 Neon-optimized palette expansion path. When...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: iio: chemical: sps30i2c: fix the buffer size in sps30i2creadmeas The value of sizeofnum is evaluated as sizeofsizet 8 bytes on 64-bit systems, instead of the intended be32 element size 4 bytes. Use sizeofmeas to correctly match t...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: smb: client: fixed the issue where krb5 mounts failed when the client tried to mount shares with incorrect credentials. It turned out that the client was reusing the SMB session from the first mount attempt, even though a differe...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: L2CAP: Verify the payload length of L2CAPINFORSP before performing the read operation. The l2capinformationrsp function checks that cmdlen covers the fixed l2capinforsp header type + result, 4 bytes. However, it the...
