In the Linux kernel, the following vulnerability has been resolved: netlink: prevents potential Spectre v1 exploits Most netlink attributes are parsed and validated via nlavalidateparse or validatenla. c u16 type = nlatypenla; if type == 0 || type maxtype / Error or continue / The @type value is...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: fs: init flagsvalid before calling vfsfileattrget syzbot reported a uninit-value bug in 1. Similar to the “get” context, where the kernel’s filekattr structure is initialized before calling vfsfileattrget, we should use the same...

Astra Linux – Vulnerability in tar

In GNU tar before version 1.35, mishandling of extension attributes in a PAX archive can cause the application to crash in xheader.c...

Astra Linux – Vulnerability in lxml

A XSS vulnerability was discovered in the clean module of python-lxml’s versions prior to 4.6.3. When the “safe attrsOnly” and “forms” arguments are disabled, the Cleaner class does not remove the “formaction” attribute, allowing JavaScript to bypass the sanitizer. A remote attacker could exploit...

Astra Linux - Vulnerability in Golang-1.19

Templates that contain actions within unquoted HTML attributes e.g., “attr=.” and are executed with an empty input can result in unexpected outputs when parsed due to HTML normalization rules. This may allow for the injection of arbitrary attributes into tags...

Astra Linux – Vulnerability in Samba

A flaw was discovered in Samba’s libldb. Multiple consecutive leading spaces in an LDAP attribute can lead to an out-of-bounds memory write, causing the LDAP server process handling the request to crash. The greatest threat of this vulnerability is to system availability...

In the Linux kernel, the following vulnerability has been resolved: ext4: fix invalid free tracking in ext4xattrMoveToBlock In ext4xattrMoveToBlock, the value of the extended attribute that we need to move to an external block may be allocated by kvmalloc if the value is stored in an external...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/xe/vf: Do not expose sysfs attributes that are not applicable to VFs. VFs cannot read the BMGPCIECAP0x138340 register, nor can they access the PCODE which is already guarded by the info.skippcode flag. Therefore, we should...

Astra Linux – Vulnerability in Samba

A vulnerability was discovered in Samba. A delegated administrator with permission to create objects in Active Directory can write to all attributes of the newly created object, including security-sensitive attributes, even after the object’s creation. This issue arises because the administrator...
