| ID: | 201401-27 |
Synopsis
A vulnerability in GNU TeXmacs could result in privilege escalation.Background
GNU TeXmacs is a free WYSIWYG editing platform with special features for scientists.
Affected packages
| Package | Vulnerable | Unaffected | Architecture(s) |
|---|---|---|---|
| app-office/texmacs | < 1.0.7.2-r1 | >= 1.0.7.2-r1 | All supported architectures |
Description
The texmacs and tm_mupad_help scripts in TeXmacs place a zero-length directory name in the LD_LIBRARY_PATH, which might result in the current working directory (.) to be included when searching for dynamically linked libraries.
Impact
A local attacker could gain escalated privileges via a specially crafted shared library.
Workaround
There is no known workaround at this time.
Resolution
All GNU TeXmacs users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/texmacs-1.0.7.2-r1"
NOTE: This is a legacy GLSA. Updates for all affected architectures are available since April 02, 2011. It is likely that your system is already no longer affected by this issue.
