NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2007-0705.NASL description Updated kernel packages that fix various security issues in the Red Hat Enterprise Linux 5 kernel are now available. This update has been rated as having important security impact by the Red Hat Security Response Team. The Linux kernel handles the basic functions of the operating system. These new kernel packages contain fixes for the following security issues : * a flaw in the DRM driver for Intel graphics cards that allowed a local user to access any part of the main memory. To access the DRM functionality a user must have access to the X server which is granted through the graphical login. This also only affected systems with an Intel 965 or later graphic chipset. (CVE-2007-3851, Important) * a flaw in the VFAT compat ioctl handling on 64-bit systems that allowed a local user to corrupt a kernel_dirent struct and cause a denial of service (system crash). (CVE-2007-2878, Important) * a flaw in the connection tracking support for SCTP that allowed a remote user to cause a denial of service by dereferencing a NULL pointer. (CVE-2007-2876, Important) * flaw in the CIFS filesystem which could cause the umask values of a process to not be honored. This affected CIFS filesystems where the Unix extensions are supported. (CVE-2007-3740, Important) * a flaw in the stack expansion when using the hugetlb kernel on PowerPC systems that allowed a local user to cause a denial of service. (CVE-2007-3739, Moderate) * a flaw in the ISDN CAPI subsystem that allowed a remote user to cause a denial of service or potential remote access.

The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2007-2172 Thomas Graf reported a typo in the IPv4 protocol handler that could be used by a local attacker to overrun an array via crafted packets, potentially resulting in a Denial of Service (system crash). The DECnet counterpart of this issue was already fixed in DSA-1356. - CVE-2007-2875 iDefense reported a potential integer underflow in the cpuset filesystem which may permit local attackers to gain access to sensitive kernel memory. This vulnerability is only exploitable if the cpuset filesystem is mounted. - CVE-2007-3105 The PaX Team discovered a potential buffer overflow in the random number generator which may permit local users to cause a denial of service or gain additional privileges. This issue is not believed to effect default Debian installations where only root has sufficient privileges to exploit it. - CVE-2007-3843 A coding error in the CIFS subsystem permits the use of unsigned messages even if the client has configured the system to enforce signing by passing the sec=ntlmv2i mount option. This may allow remote attackers to spoof CIFS network traffic. - CVE-2007-4308 Alan Cox reported an issue in the aacraid driver that allows unprivileged local users to make ioctl calls which should be restricted to admin privileges.

(CVE-2007-3843) It was discovered that certain setuid-root processes did not correctly reset process death signal handlers. A local user could manipulate this to send signals to processes they would not normally have access to. (CVE-2007-3848) The Direct Rendering Manager for the i915 driver could be made to write to arbitrary memory locations. An attacker with access to a running X11 session could send a specially crafted buffer and gain root privileges. (CVE-2007-3851) It was discovered that the aacraid SCSI driver did not correctly check permissions on certain ioctls. A local attacker could cause a denial of service or gain privileges. (CVE-2007-4308). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 28114 published 2007-11-10 reporter Ubuntu Security Notice (C) 2007-2019 Canonical, Inc. / NASL script (C) 2007-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/28114 title Ubuntu 7.04 : linux-source-2.6.20 vulnerabilities (USN-510-1) NASL family SuSE Local Security Checks NASL id SUSE_KERNEL-4741.NASL description This 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. (CVE-2007-4308) - 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.
