[GLSA-200411-05] libxml2: Remotely exploitable buffer overflow |
||
libxml2: Remotely exploitable buffer overflow Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200411-05 (libxml2: Remotely exploitable buffer overflow) Multiple buffer overflows have been detected in the nanoftp and nanohttp modules. These modules are responsible for parsing URLs with ftp information, and resolving names via DNS. Impact A possible hacker could exploit an application that uses libxml2 by forcing it to parse a specially-crafted XML file, potentially causing remote execution of arbitrary code. Workaround There is no known workaround at this time.
