high Nessus Plugin ID 39363
Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
Matthew Palmer discovered an underflow flaw in apr-util. An attacker could cause a denial of service via application crash in Apache using a crafted SVNMasterURI directive, .htaccess file, or when using mod_apreq2. Applications using libapreq2 are also affected.(CVE-2009-0023)
It was discovered that the XML parser did not properly handle entity expansion. A remote attacker could cause a denial of service via memory resource consumption by sending a crafted request to an Apache server configured to use mod_dav or mod_dav_svn. (CVE-2009-1955)
C. Michael Pilato discovered an off-by-one buffer overflow in apr-util when formatting certain strings. For big-endian machines (powerpc, hppa and sparc in Ubuntu), a remote attacker could cause a denial of service or information disclosure leak. All other architectures for Ubuntu are not considered to be at risk. (CVE-2009-1956).
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.
Solution
Update the affected libaprutil1, libaprutil1-dbg and / or libaprutil1-dev packages.See Also
