SuSE 10 Security Update : Linux kernel (ZYPP Patch Number 4745)
High Nessus Plugin ID 59125
SynopsisThe remote SuSE 10 host is missing a security-related patch.
DescriptionThis kernel update fixes the following security problems :
- The sysfs_readdir function in the Linux kernel 2.6 allows local users to cause a denial of service (kernel OOPS) by dereferencing a NULL pointer to an inode in a dentry. (CVE-2007-3104)
- A 2 byte buffer underflow in the ieee80211 stack was fixed, which might be used by attackers in the local WLAN reach to crash the machine. (CVE-2007-4997)
- The CIFS filesystem, when Unix extension support is enabled, did not honor the umask of a process, which allowed local users to gain privileges. (CVE-2007-3740)
- It was possible for local user to become root by exploiting a bug in the IA32 system call emulation. This problem affects the x86_64 platform only, on all distributions. (CVE-2007-4573)
This problem was fixed for regular kernels, but had not been fixed for the XEN kernels. This update fixes the problem also for the XEN kernels.
- The (1) aac_cfg_open and (2) aac_compat_ioctl functions in the SCSI layer ioctl path in aacraid did not check permissions for ioctls, which might have allowed local users to cause a denial of service or gain privileges.
- The Linux kernel checked the wrong global variable for the CIFS sec mount option, which might allow remote attackers to spoof CIFS network traffic that the client configured for security signatures, as demonstrated by lack of signing despite sec=ntlmv2i in a SetupAndX request. (CVE-2007-3843)
- Multiple buffer overflows in CIFS VFS in the Linux kernel allowed remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via long SMB responses that trigger the overflows in the SendReceive function. (CVE-2007-5904)
This requires the attacker to mis-present / replace a CIFS server the client machine is connected to.
- Buffer overflow in the isdn_net_setcfg function in isdn_net.c in the Linux kernel allowed local users to have an unknown impact via a crafted argument to the isdn_ioctl function. (CVE-2007-6063)
