CVE-2025-32797 Conda-build Insecure Build Script Permissions Enabling Arbitrary Code Execution

Conda-build contains commands and tools to build conda packages. Prior to version 25.3.1, the writebuildscripts function in conda-build creates the temporary build script condabuild.sh with overly permissive file permissions 0o766, allowing write access to all users. Attackers with filesystem...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: NFSv4: A deadlock occurs when recovering state on a file that has been renamed.

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: jfs: fixed a slab-out-of-bounds read in eaget During the “sizecheck” step in eaget, the code checks whether the extended attribute list xattr size matches easize. If not, it logs “eaget: invalid extended attribute” and calls...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ubifs: Skip dumping the tnc tree when zroot is null. Clearing the slab cache will free all znode entries in memory, and set c-zroot.znode to NULL. Dumping the tnc tree will then access c-zroot.znode, which can lead to a null...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: afs: Fixed the maximum length of cell names. The kafs filesystem limits the maximum length of a cell to 256 bytes. However, a problem arises when someone attempts to create a directory under /proc/net/afs/ with the name of a cell...

Astra Linux – Vulnerability in grub2

When reading data from an HFS filesystem, Grub’s HFS filesystem module uses user-controlled parameters from the filesystem metadata to calculate the internal buffer size. However, it fails to properly check for integer overflows. A maliciously crafted filesystem may cause some of those buffer siz...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ocfs2: Fixed a slab-use-after-free issue caused by a dangling pointer dqipriv. When mounting ocfs2 and then remounting it as read-only, a slab-use-after-free occurs after the user uses the syscall to call ocfs2getnextid...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: fs/ntfs3: Fixed a couple of integer overflows on 32-bit systems. On 32-bit systems, the addition of “off + sizeofstruct NTFSDE” can lead to an integer wrapping issue. This issue was fixed by using sizeadd...

In the Linux kernel, the following vulnerability has been resolved: f2fs: fixed to avoid accessing uninitialized curseg. The syzbot reports the following f2fs bug: F2FS-fs loop3: The filesystem stopped due to the reason: 7. kworker/u8:7: Attempt to access beyond the end of the device. Bug: Unable...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: NFSD: fixed a hang issue in nfsd4shutdowncallback. If nfs4client is in the courtesy state, there is no point in sending the callback. This causes nfsd4shutdowncallback to hang, as clcbinflight is not set to 0. This hang lasts...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: NFS: Fixed a potential buffer overflow in nfssysfslinkrpcclient. The name field is defined as char64, and the size of clnt-clprogram-name remains unknown. Invoking strcat directly will also lead to a potential buffer overflow...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: nfsd: The value of sccount is decreased directly if the dlrecall queue operation fails. A deadlock warning occurred when invoking nfs4putstid after a failed dlrecall queue operation: T1 T2 nfs4laundromat nfs4getclientreaplist...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: netfs: Only create /proc/fs/netfs with CONFIGPROCFS enabled.
