A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from the CVE list The nfs-utils packages provide a daemon for the kernel Network File System...

kernel: NFSD: Protect against send buffer overflow in NFSv2 READDIR

In the Linux kernel, the following vulnerability has been resolved: NFSD: Protect against send buffer overflow in NFSv2 READDIR Restore the previous limit on the @count argument to prevent a buffer overflow attack...

kernel: nfsd buffer overflow by RPC message over TCP with garbage data

A buffer overflow flaw was found in the Linux kernel nfsd network file system subsystem. The way a user sends RPC over TCP with excess data added at the end of the message could allow a remote user to starve the resources, causing a denial of service...

kernel: NFSD: Protect against send buffer overflow in NFSv3 READDIR

A buffer management flaw was found in the Linux kernel's NFS server implementation in the NFSv3 READDIR operation handling. A remote client can trigger this issue by crafting an RPC call with an oversized RPC record header, which forces the server to shrink its response buffer allocation. This...

PT-2025-40674

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the Linux kernel's Network File System Daemon NFSD related to handling RPC calls in NFSv3 READDIR operations. The issue stems from a potential send buffer overflow that...

SUSE CVE-2004-0497

Unknown vulnerability in Linux kernel 2.x may allow local users to modify the group ID of files, such as NFS exported files in kernel 2.4...

SUSE CVE-2004-0946

rquotad in nfs-utils rquotaserver.c before 1.0.6-r6 on 64-bit architectures does not properly perform an integer conversion, which leads to a stack-based buffer overflow and allows remote attackers to execute arbitrary code via a crafted NFS request...

SUSE CVE-2005-3623

nfs2acl.c in the Linux kernel 2.6.14.4 does not check for MAYSATTR privilege before setting access controls ACL on files on exported NFS filesystems, which allows remote attackers to bypass ACLs for readonly mounted NFS filesystems...

SUSE CVE-2005-4798

Buffer overflow in NFS readlink handling in the Linux Kernel 2.4 up to 2.4.31 allows remote NFS servers to cause a denial of service crash via a long symlink, which is not properly handled in 1 nfs2xdr.c or 2 nfs3xdr.c and causes a crash in the NFS client...

SUSE CVE-2006-3468

Linux kernel 2.6.x, when using both NFS and EXT3, allows remote attackers to cause a denial of service file system panic via a crafted UDP packet with a V2 lookup procedure that specifies a bad file handle inode number, which triggers an error and causes an exported directory to be remounted...

SUSE CVE-2006-3632

Buffer overflow in Wireshark aka Ethereal 0.8.16 to 0.99.0 allows remote attackers to cause a denial of service and possibly execute arbitrary code via the NFS dissector...

SUSE CVE-2007-3207

Buffer overflow in the NFS mount daemon XNFS.NLM in Novell NetWare 6.5 SP6, and probably earlier, allows remote attackers to cause a denial of service abend via a long path in a mount request...

SUSE CVE-2007-4135

The NFSv4 ID mapper nfsidmap before 0.17 does not properly handle return values from the getpwnamr function when performing a username lookup, which can cause it to report a file as being owned by "root" instead of "nobody" if the file exists on the server but not on the client...

SUSE CVE-2008-3915

Buffer overflow in nfsd in the Linux kernel before 2.6.26.4, when NFSv4 is enabled, allows remote attackers to have an unknown impact via vectors related to decoding an NFSv4 acl...

SUSE CVE-2009-1072

nfsd in the Linux kernel before 2.6.28.9 does not drop the CAPMKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the rootsquash option...

SUSE CVE-2009-1630

The nfspermission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel 2.6.29.3 and earlier, when atomicopen is available, does not check execute aka EXEC or MAYEXEC permission bits, which allows local users to bypass permissions and execute files, as demonstrated by file...

SUSE CVE-2009-3623

The lookupcbcred function in fs/nfsd/nfs4callback.c in the nfsd4 subsystem in the Linux kernel before 2.6.31.2 attempts to access a credentials cache even when a client specifies the AUTHNULL authentication flavor, which allows remote attackers to cause a denial of service NULL pointer dereferenc...

SUSE CVE-2010-1087

The nfswaitonrequest function in fs/nfs/pagelist.c in Linux kernel 2.6.x through 2.6.33-rc5 allows attackers to cause a denial of service Oops via unknown vectors related to truncating a file and an operation that is not interruptible...

SUSE CVE-2010-2521

Multiple buffer overflows in fs/nfsd/nfs4xdr.c in the XDR implementation in the NFS server in the Linux kernel before 2.6.34-rc6 allow remote attackers to cause a denial of service panic or possibly execute arbitrary code via a crafted NFSv4 compound WRITE request, related to the readbuf and...

SUSE CVE-2010-2943

The xfs implementation in the Linux kernel before 2.6.35 does not look up inode allocation btrees before reading inode buffers, which allows remote authenticated users to read unlinked files, or read or overwrite disk blocks that are currently assigned to an active file but were previously assign...
