A security vulnerability exists in Olgu Computer Systems e-Belediye prior to version 2.0.642, which arises from incorrect privilege assignment of externally controlled filenames or paths, and allows manipulation of Web...

Ubuntu 20.04 LTS : Linux kernel vulnerabilities (USN-7009-2)

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7009-2 advisory. Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to caus...

kernel: NFSv4: Fix memory leak in nfs4_set_security_label

A vulnerability was found in the nfs4setsecuritylabel in the Linux kernel, where the function fails to free the nfsfattr attribute before exiting, leaving said memory allocation present. As the nfs4setsecuritylabel is called repeatedly over time, this may lead to memory exhaustion...

kernel: gfs2: Fix potential glock use-after-free on unmount

A vulnerability was found in the Linux kernel within the gfs2 component, where potential use-after-free issues could occur on unmount. When DLM lockspaces are released with remaining locks, callbacks for asynchronous lock contention may access freed objects, causing unexpected behavior...

kernel: ftruncate: pass a signed offset

An unexpected file truncate flaw was found when opening files with specific parameters in the Linux kernel's file-system. This vulnerability allows a local user to corrupt specific files when having access to these files...

kernel: NFSv4: Don't hold the layoutget locks across multiple RPC calls

In the Linux kernel, the following vulnerability has been resolved: NFSv4: Don't hold the layoutget locks across multiple RPC calls When doing layoutget as part of the open compound, we have to be careful to release the layout locks before we can call any further RPC calls, such as setattr. The...

kernel: gfs2: Fix potential glock use-after-free on unmount

A vulnerability was found in the Linux kernel within the gfs2 component, where potential use-after-free issues could occur on unmount. When DLM lockspaces are released with remaining locks, callbacks for asynchronous lock contention may access freed objects, causing unexpected behavior...

kernel: xfs: add bounds checking to xlog_recover_process_data

A vulnerability has been identified within the Linux kernel's xlogrecoverprocessdata function. Specifically, the function lacks proper bounds checking on the space allocated for the fixed members of the xlogopheader structure during log record processing. This omission can lead to an out-of-bound...

kernel: xfs: don't walk off the end of a directory data block

A vulnerability was found in the Linux kernel in the xfsdir2dataunused and xfsdir2dataentry functions where a lack of proper sanity checks while handling directory data blocks can lead to out-of-bounds memory access. This can result in undefined system behavior or crashes...

kernel: NFSD: Fix ia_size underflow

A vulnerability was found in the Linux kernel's NFSD, where an underflow in the iasize field can occur due to incorrect handling of file size types. When an NFS client sends a file size greater than the maximum value the system can handle, it can lead to an underflow in the iasize variable, causi...

kernel: NFSD: Fix NFSv3 SETATTR/CREATE's handling of large file sizes

A vulnerability was found in the Linux kernel's NFSD, specifically in the handling of large file sizes during NFSv3 SETATTR and CREATE operations. The iasize field, being a signed 64-bit type, can lead to unexpected behavior when clients send size values larger than the maximum allowed. This...

The vulnerability of the btrfs component of the Linux operating system’s kernel, related to writing beyond the memory boundaries, allows a hacker to trigger a service failure.

The vulnerability of the btrfs component in Linux operating systems relates to the copying of overly large compressed segments. The compressed length may be corrupted, resulting in a much larger amount of memory being allocated for the buffer. Exploiting this vulnerability can allow an attacker t...
