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. Prior to version 1.6.55, there was an out-of-bounds read vulnerability in the pngsetquantize API function. When this function is called without a histogram and th...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: LZ4: fixed the issue of partial reading beyond the bounds of the buffer during decoding. During partialDecoding, an EOF occurs if either the output buffer is full or if reading further beyond the offset is not possible. In some...

Astra Linux – Vulnerability in xwayland, xorg-server

A buffer overflow vulnerability was discovered in X.Org and Xwayland. The code in XkbVModMaskText allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and will copy the data regardless of the siz...

In the Linux kernel, the following vulnerabilities have been resolved: fs: udf: Fix for OOB read in lengthAllocDescs handling When parsing the Allocation Extent Descriptor, lengthAllocDescs is derived from disk-based data and must be validated against the block size. Corrupted or crafted images m...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ipv6: A buffer overflow vulnerability has been addressed in ipv6findtlv. The value of optlen is retrieved without checking whether there are more than one bytes to parse. This can lead to a buffer overflow attack. This issue was...

Astra Linux – Vulnerability in binutils

A vulnerability was discovered in GNU Binutils 2.45. The affected function is bfdx86elflatesizesections in the file bfd/elfxx-x86.c of the Linker component. This vulnerability leads to out-of-bounds read attacks. The attack must be approached locally. The exploit has been made public and can be...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: s390/cio: Fixed an out-of-bounds access issue related to the cioignore function.
