Astra Linux – Vulnerability in Less

The value “less through 653” allows for OS command execution via a newline character in the file name, due to improper handling of quotes in the filename.c file. Exploitation typically requires the use of file names controlled by the attacker, such as those extracted from untrusted archives...

Astra Linux – Vulnerability in exim4

Exim 4 before 4.94.2 allowed execution with unnecessary privileges. Since Exim operates as root in the spool directory owned by a non-root user, an attacker could write to the /var/spool/exim4/input spool header file. A crafted recipient address in that file could indirectly lead to command...

Astra Linux – Vulnerability in Redis

Redis is an open-source, in-memory database that persists data on disk. A integer overflow bug in the ziplist data structure used in all versions of Redis can be exploited to corrupt the heap and potentially lead to remote code execution. The vulnerability involves modifying the default ziplist...

Astra Linux – Vulnerability in jq

jq is a command-line JSON processor. A integer overflow vulnerability exists in versions 1.8.1 and later, within the jvpstring.Append and jvpstringCopyReplaceBad functions. Concatenating strings whose combined length exceeds 2^31 bytes causes a 32-bit unsigned integer overflow in the buffer...

Astra Linux – Vulnerability in Node.js

A OS command injection vulnerability exists in Node.js versions 14.20.0, 16.20.0, 18.5.0 due to an insufficient IsAllowedHost check. This vulnerability can be easily exploited, as the IsIPAddress function does not properly check whether an IP address is invalid before making DBS requests, thereby...
