libwmf is a library for converting WMF files.
Multiple vulnerabilities have been discovered in libwmf. Please review the CVE identifiers referenced below for details.
A remote attacker could possibly execute arbitrary code with the privileges of the process or cause Denial of Service.
There is no known work around at this time.
All libwmf users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libwmf-0.2.8.4-r6"
libwmf bundles an old GD version which contains a "use-after-free" vulnerability.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| media-libs/libwmf | * | < 0.2.8.4-r3 | >= 0.2.8.4-r3 |
libwmf is a library for converting WMF files.
The embedded fork of the GD library introduced a "use-after-free" vulnerability in a modification which is specific to libwmf.
A remote attacker could entice a user to open a specially crafted WMF file, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.
There is no known workaround at this time.
All libwmf users should upgrade to the latest version which no longer builds the GD library:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libwmf-0.2.8.4-r3"
libwmf is vulnerable to an integer overflow potentially resulting in the execution of arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| media-libs/libwmf | * | < 0.2.8.4 | >= 0.2.8.4 |
libwmf is a library for reading and converting vector images in Microsoft's native Windows Metafile Format (WMF).
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.
All libwmf users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libwmf-0.2.8.4"
