Astra Linux – Vulnerability in libgcrypt20

The ElGamal implementation in Libgcrypt before version 1.9.4 allows plaintext recovery. This occurs because, during interaction between two cryptographic libraries, a dangerous combination of elements arises—specifically, the prime number defined by the receiver’s public key, the generator define...

Astra Linux – Vulnerability in Redis

Redis is an in-memory database that persists data on disk. A vulnerability exists starting from version 2.2, and is related to out-of-bounds reads and integer overflow leading to buffer overflow. This vulnerability is present in versions 5.0.13, 6.0.15, and 6.2.5. On 32-bit systems, the Redis BIT...

Astra Linux – Vulnerability in libproxy

In libproxy, the url.cpp module in version 0.4.15 is vulnerable to a buffer overflow when PAC is enabled. This vulnerability was confirmed by using a large PAC file that was sent without a Content-length header...

Astra Linux – Vulnerability in pyxdg

A code injection issue was discovered in PyXDG before version 0.26, through crafted Python code within a Category element of a Menu XML document in a .menu file. The XDGCONFIGDIRS setting must be configured to trigger the xdg.Menu.parse parsing within the directory containing this file. This issu...

Astra Linux – Vulnerability in sudo

A flaw was discovered in sudo’s handling of ipahostname. In this process, the ipahostname value from /etc/sssd/sssd.conf was not propagated to sudo. As a result, this leads to a privilege management vulnerability in applications, where client hosts retain privileges even after those privileges ha...

Astra Linux – Vulnerability in connman

The client.c file in gdhcp within ConnMan, as of version 1.41, can be exploited by network-adjacent attackers who operate a crafted DHCP server. This exploitation can lead to a stack-based buffer overflow and a denial of service attack, resulting in the termination of the connman process...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: L2CAP: Fix for u8 overflow By continuously sending L2CAPCONFREQ packets, chan-numconfrsp increases multiple times, eventually exceeding the maximum number i.e., 255. This patch prevents this issue by adding a bounda...

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

In the Linux kernel, the following vulnerability has been resolved: In md/raid10, there is a issue where memory leaks occur in the MD thread. In raid10run, if setupconf succeeds and raid10run fails before setting ‘mddev-thread’, then the variable ‘conf-thread’ is not freed after the failure. This...

Astra Linux – Vulnerability in edk2

EDK2’s Network Package is vulnerable to a buffer overflow vulnerability when handling the Server ID option from a DHCPv6 proxy Advertise message. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of Confidentiality, Integrity, and/or...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/i915/vrr: Configure VRR timings after enabling TRANSDDIFUNCCTL It appears that the ICL may hang when using an MCE if we set TRANSVRRVMAX/FLIPLINE before enabling TRANSDDIFUNCCTL. Personally, I was only able to reproduce such ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: x86/resctrl: Clear stagedconfig before and after it is used. As a temporary storage, stagedconfig in rdtdomain should be cleared before and after it is used. The stale value in stagedconfig could cause an MSR access error. Here i...

In the Linux kernel, the following vulnerability has been resolved: mm/uffd: A warning is now prevented when PTE MARKERUFFDWP is not compiled in. When PTE MARKERUFFDWP is not configured, it’s still possible to access the pte marker code and trigger a warning. Add some CONFIGPTE MARKERUFFDWP ifdef...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ACPI: CPPC: Use accesswidth instead of bitwidth for system memory accesses To comply with ACPI 6.3+, since bitwidth can be any 8-bit value, it cannot be relied upon to always be at a clean 8-bit boundary. This issue was discovere...

Astra Linux – Vulnerability in glibc

A flaw has been identified in glibc. In a rare situation, the gaihinet function may use memory that has already been freed, leading to an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with...
