Texinfo is vulnerable to a buffer overflow that could lead to the execution of arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| sys-apps/texinfo | * | < 4.8-r5 | >= 4.8-r5 |
Texinfo is the official documentation system of the GNU project.
Miloslav Trmac from Red Hat discovered a buffer overflow in the "readline()" function of texindex.c. The "readline()" function is called by the texi2dvi and texindex commands.
By enticing a user to open a specially crafted Texinfo file, an attacker could execute arbitrary code with the rights of the user running Texinfo.
There is no known workaround at this time.
All Texinfo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/texinfo-4.8-r5"
Texinfo is vulnerable to symlink attacks, potentially allowing a local user to overwrite arbitrary files.

Texinfo is the official documentation system created by the GNU project.
Frank Lichtenheld has discovered that the "sort_offline()" function in texindex insecurely creates temporary files with predictable filenames.
A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When texindex is executed, this would result in the file being overwritten with the rights of the user running the application.
There is no known workaround at this time.
All Texinfo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/texinfo-4.8-r1"
