PLATFORM: For the stable distribution (sarge) fixed in version 1.2.10-15sarge3 For the unstable distribution (sid) fixed in version 1.3.0-16 of the proftpd-dfsg package DAMAGE: It was discovered that a buffer overflow in the mod_tls addon module may lead to the execution of arbitrary code and a buffer overflow in the sreplace() function may lead to denial of service and possibly the execution of arbitrary code. SOLUTION: Apply current patches. ______________________________________________________________________________ VULNERABILITY The risk is MEDIUM. May lead to the execution of arbitrary ASSESSMENT: code. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/r-062.shtml ORIGINAL BULLETIN: http://www.debian.org/security/2006/dsa-1222 CVE: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CVE-2006-5815, CVE-2006-6170, CVE-2006-6171 ______________________________________________________________________________ [***** Start DSA-1222-1 *****] Debian Security Advisory DSA-1222-1 proftpd -- several vulnerabilities Date Reported: 30 Nov 2006 Affected Packages: proftpd Vulnerable: Yes Security database references: In the Debian bugtracking system: Bug 399070. In Mitre's CVE dictionary: CVE-2006-5815, CVE-2006-6170, CVE-2006-6171. More information: Several remote vulnerabilities have been discovered in the proftpd FTP daemon, which may lead to the execution of arbitrary code or denial of service. The Common Vulnerabilities and Exposures project identifies the following problems: * CVE-2006-5815 It was discovered that a buffer overflow in the sreplace() function may lead to denial of service and possibly the execution of arbitrary code. * CVE-2006-6170 It was discovered that a buffer overflow in the mod_tls addon module may lead to the execution of arbitrary code. * CVE-2006-6171 It was discovered that insufficient validation of FTP command buffer size limits may lead to denial of service. Due to unclear information this issue was already fixed in DSA-1218 as CVE-2006-5815. For the stable distribution (sarge) these problems has been fixed in version 1.2.10-15sarge3. For the unstable distribution (sid) these problems has been fixed in version 1.3.0-16 of the proftpd-dfsg package. We recommend that you upgrade your proftpd package.
