GLSA-200608-17 : libwmf: Buffer overflow vulnerability
High Nessus Plugin ID 22216
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200608-17 (libwmf: Buffer overflow vulnerability)
infamous41md discovered that libwmf fails to do proper bounds checking on the MaxRecordSize variable in the WMF file header. This could lead to an head-based buffer overflow.
By enticing a user to open a specially crafted WMF file, a remote attacker could cause a heap-based buffer overflow and execute arbitrary code with the permissions of the user running the application that uses libwmf.
There is no known workaround for this issue.
SolutionAll libwmf users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libwmf-0.2.8.4'
