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

In the Linux kernel, the following vulnerability has been resolved: kheaders: Use an array declaration instead of a char. Under CONFIGFORTIFYSOURCE, memcpy will check the size of the destination and source buffers. Defining kernelheadersdata as “char” would trigger this check. Since these address...

Astra Linux – Vulnerability in TIF format

A null source pointer passed as an argument to the memcopy function within TIFFFetchStripThing in tifdirread.c in libtiff versions from 3.9.0 to 4.3.0 could lead to a Denial of Service attack through a crafted TIFF file. For users who compile libtiff from source code, this fix is available in the...

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

A out-of-bounds write vulnerability was discovered in the Linux kernel’s SLIMpro I2C device driver. The userspace variable “data-block0” was not bounded to a value between 0 and 255; instead, it was used as the size for a memcpy operation, potentially leading to data writing beyond the bounds of...
