A vulnerability in GNU TeXmacs could result in privilege escalation.
|Package||app-office/texmacs on all architectures|
|Affected versions||< 220.127.116.11-r1|
|Unaffected versions||>= 18.104.22.168-r1|
GNU TeXmacs is a free WYSIWYG editing platform with special features for scientists.
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.
A local attacker could gain escalated privileges via a specially crafted shared library.
There is no known workaround at this time.
All GNU TeXmacs users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-office/texmacs-22.214.171.124-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.
