Synopsis
A vulnerability in Netpbm could result in execution of arbitrary code or Denial of Service.Background
Netpbm is a toolkit for manipulation of graphic images, including conversion of images between a variety of different formats.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
media-libs/netpbm | < 10.49.00 | >= 10.49.00 | All supported architectures |
Description
A stack-based buffer overflow exists in converter/ppm/xpmtoppm.c in Netpbm.
Impact
A remote attacker could entice a user to open a specially crafted XMP file using Netpbm, possibly resulting in execution of arbitrary code with the privileges of the process, or a Denial of Service condition.
Workaround
There is no known workaround at this time.
Resolution
All Netpbm users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/netpbm-10.49.00"
Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
