Test ID:	1.3.6.1.4.1.25623.1.0.50309
Category:	Fedora Local Security Checks
Title:	Fedora Core 1 FEDORA-2004-111 (kernel)
Summary:	NOSUMMARY
Description:	Description: The remote host is missing an update to kernel announced via advisory FEDORA-2004-111. The kernel package contains the Linux kernel (vmlinuz), the core of your Fedora Core Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc. Update Information: A memory leak was fixed in an error path in the do_fork() routine. This was unlikely to have caused problems in real world situations. The information leak fixed in the previous errata was also found to affect XFS and JFS. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the names CVE-2004-0133 and CVE-2004-0181 respectively. A vulnerability in the OSS code for SoundBlaster 16 devices was discovered by Andreas Kies. It is possible for local users with access to the sound system to crash the machine (CVE-2004-0178). An automated checked from http://www.coverity.com highlighted a range checking bug in the i810 DRM driver. This was fixed by Andrea Arcangeli and Chris Wright. Arjan van de Ven discovered the framebuffer code was doing direct userspace accesses instead of using correct interfaces to write to userspace. Brad Spengler found a signedness issue in the cpufreq proc handler which could lead to users being able to read arbitary regions of kernel memory. This was fixed by Dominik Brodowski. Shaun Colley found a potential buffer overrun in the panic() function. As this function does not ever return, it is unlikely that this is exploitable, but has been fixed nonetheless. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2004-0394 to this issue. Paul Starzetz and Wojciech Purczynski found a lack of bounds checking in the MCAST_MSFILTER socket option which allows user code to write into kernel space, potentially giving the attacker full root priveledges. There has already been proof of concept code published exploiting this hole in a local denial-of-service manner. http://www.isec.pl/vulnerabilities/isec-0015-msfilter.txt has more information. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2004-0424 to this issue. The previous security errata actually missed fixes for several important problems. This has been corrected in this update. * Wed Apr 21 2004 Dave Jones - Fix memory leak in do_fork() error path - Really fix CVE-2004-0109 and previous mremap issue. These patches were not applied in the previous errata. - Fix information leak in XFS (CVE-2004-0133) - Fix potential local denial of service in sb16 driver (CVE-2004-0178) - Fix information leak in JFS (CVE-2004-0181) - Add range checking to i810_dma() in DRM driver. - Make ioctl(FBIOGETCMAP) use copy_to_user() rather than memcpy() - Fix information leak in cpufreq userspace ioctl. (CVE-2004-0228) - Fix possible buffer overflow in panic() (CVE-2004-0394) - Fix setsockopt MCAST_MSFILTER integer overflow. (CVE-2004-0424) Solution: Apply the appropriate updates. http://www.fedoranews.org/updates/FEDORA-2004-111.shtml Risk factor : Medium CVSS Score: 2.1
