Security announcements for Frugalware stable releases http://frugalware.org/security http://bugs.frugalware.org/task/3050 http://bugs.frugalware.org/task/3050#top A vulnerability has been reported in the Linux kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service) or to potentially gain escalated privileges. A race condition error exists in the dnotify subsystem between calls to "fcntl()" and "close()". This can be exploited to cause a system crash or potentially gain root privileges.Vulnerable version: 2.6.24-3, Unaffected version: 2.6.24-4kalgan1, CVEs: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1375 Mon, 05 May 2008 00:00:00 +0200 http://bugs.frugalware.org/task/3052 http://bugs.frugalware.org/task/3052#top A vulnerability has been reported in frugalwareutils, which can potentially be exploited by malicious people to cause a DoS on a vulnerable system. The vulnerability is caused due to creating new files as root without checking the current value of umask. Successful exploitation may allow execution of arbitrary code.Vulnerable version: 0.7.9-1, Unaffected version: 0.7.9-2kalgan1, CVEs: There is no CVE for this issue. Mon, 05 May 2008 00:00:00 +0200 http://bugs.frugalware.org/task/3032 http://bugs.frugalware.org/task/3032#top A vulnerability has been reported in vorbis-tools, which can potentially be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to the use of vulnerable libfishsound; an input validation error when processing Speex headers, which can be exploited via a specially crafted Speex stream containing a negative "modeID" field in the header. Successful exploitation may allow execution of arbitrary code.Vulnerable version: 1.1.1-3, Unaffected version: 1.1.1-4kalgan1, CVEs: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1686 Mon, 05 May 2008 00:00:00 +0200 http://bugs.frugalware.org/task/3027 http://bugs.frugalware.org/task/3027#top Guido Landi has discovered a vulnerability in xine-lib, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused due to a boundary error within the "demux_nsf_send_chunk()" function in src/demuxers/demux_nsf.c. This can be exploited to cause a stack-based buffer overflow via an overly long NSF title.Vulnerable version: 1.1.11-1kalgan2, Unaffected version: 1.1.11-1kalgan3, CVEs: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1878 Mon, 05 May 2008 00:00:00 +0200 http://bugs.frugalware.org/task/3010 http://bugs.frugalware.org/task/3010#top A vulnerability has been reported in xine-lib, which can potentially be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to the use of vulnerable libfishsound; an input validation error when processing Speex headers, which can be exploited via a specially crafted Speex stream containing a negative "modeID" field in the header. Successful exploitation may allow execution of arbitrary code.Vulnerable version: 1.1.11-1kalgan2, Unaffected version: 1.1.11-1kalgan3, CVEs: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1686 Mon, 05 May 2008 00:00:00 +0200 http://bugs.frugalware.org/task/3035 http://bugs.frugalware.org/task/3035#top A vulnerability has been reported in phpMyAdmin, which can be exploited by malicious users to disclose sensitive information. The vulnerability is caused due to an unspecified error and can be exploited to disclose arbitrary files via a specially crafted HTTP POST request. Successful exploitation requires a certain level of access e.g. on a shared host.Vulnerable version: 2.11.5.1-1kalgan1, Unaffected version: 2.11.5.2-1kalgan1, CVEs: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1924 Fri, 25 Apr 2008 00:00:00 +0200 http://bugs.frugalware.org/task/2961 http://bugs.frugalware.org/task/2961#top A weakness has been reported in OpenSSH, which can be exploited by malicious, local users to bypass certain security restrictions. The weakness is caused due to the improper implementation of the "ForceCommand" directive. This can be exploited to execute arbitrary commands via the ~/.ssh/rc file even if a "ForceCommand" directive is in effect.Vulnerable version: 4.7p1-4kalgan1, Unaffected version: 4.7p1-4kalgan2, CVEs: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1657 Fri, 25 Apr 2008 00:00:00 +0200 http://bugs.frugalware.org/task/3013 http://bugs.frugalware.org/task/3013#top Tavis Ormandy has reported a vulnerability in libpng, which can be exploited by malicious people to cause a DoS (Denial of Service), disclose potentially sensitive information, or potentially compromise an application using the library. The vulnerability is caused due to the improper handling of PNG chunks unknown to the library. This can be exploited to trigger the use of uninitialized memory in e.g. a "free()" call via unknown PNG chunks having a length of zero. Successful exploitation may allow execution of arbitrary code, but requires that the application calls the "png_set_read_user_chunk_fn()" function or the "png_set_keep_unknown_chunks()" function under specific conditions.Vulnerable version: 1.2.24-1, Unaffected version: 1.2.24-2kalgan1, CVEs: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1382 Fri, 25 Apr 2008 00:00:00 +0200 http://bugs.frugalware.org/task/3012 http://bugs.frugalware.org/task/3012#top Thomas Pollet has reported a vulnerability in CUPS, which potentially can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to two integer overflow errors in filter/image-png.c when processing PNG files. These can be exploited to cause a heap-based buffer overflow via overly large width and height PNG fields. Successful exploitation may allow execution of arbitrary code.Vulnerable version: 1.3.6-2kalgan1, Unaffected version: 1.3.6-2kalgan2, CVEs: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1722 Fri, 25 Apr 2008 00:00:00 +0200 http://bugs.frugalware.org/task/3014 http://bugs.frugalware.org/task/3014#top Some vulnerabilities have been reported in ClamAV, which can be exploited by malicious people to bypass certain security restrictions, to cause a DoS (Denial of Service), or to compromise a vulnerable system. 1) A boundary error exists within the "cli_scanpe()" function in libclamav/pe.c. This can be exploited to cause a heap-based buffer overflow via a specially crafted "Upack" executable. Successful exploitation allows execution of arbitrary code. 2) A boundary error within the processing of PeSpin packed executables in libclamav/spin.c can be exploited to cause a heap-based buffer overflow. Successful exploitation may allow execution of arbitrary code. 3) An unspecified error in the processing of ARJ files can be exploited to hang ClamAV. 4) A boundary error within the processing of WWPack packed PE files in libclamav/pe.c can be exploited to cause a heap corruption. Successful exploitation may allow execution of arbitrary code. 5) An error in the processing of RAR files can be exploited to bypass the scanning mechanism via a RAR file containing an invalid version number. 6) An error exists within the "rfc2231()" function in message.c. This can be exploited to trigger the return of strings that are not NULL terminated and cause a crash. 7) An error in libclamunrar can be exploited to crash the application via specially crafted RAR files.Vulnerable version: 0.92.1-1, Unaffected version: 0.93-1kalgan1, CVEs: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1100 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0314 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1387 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1833 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1835 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1836 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1837 Fri, 25 Apr 2008 00:00:00 +0200
