Vulnerabilidades

The SyncTeX parser (synctex_parser.c) shipped with TeX Live and embedded by downstream consumers such as GNOME Evince contains a heap use-after-free vulnerability that allows attackers to crash applications or potentially execute arbitrary code by supplying a malformed .synctex or .synctex.gz file. A malformed SyncTeX…

TeX Live 944e257 allows a NULL pointer dereference in texk/web2c/pdftexdir/tounicode.c. NOTE: this is disputed because it should be categorized as a usability problem.

LuaTeX before 1.17.0 allows execution of arbitrary shell commands when compiling a TeX file obtained from an untrusted source. This occurs because luatex-core.lua lets the original io.popen be accessed. This also affects TeX Live before 2023 r66984 and MiKTeX before 23.5.

LuaTeX before 1.17.0 allows a document (compiled with the default settings) to make arbitrary network requests. This occurs because full access to the socket library is permitted by default, as stated in the documentation. This also affects TeX Live before 2023 r66984 and MiKTeX before 23.5.

An issue was discovered in t1_check_unusual_charstring functions in writet1.c files in TeX Live before 2018-09-21. A buffer overflow in the handling of Type 1 fonts allows arbitrary code execution when a malicious font is loaded by one of the vulnerable tools: pdflatex, pdftex, dvips, or luatex.

TeX Live through 20170524 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL, related to linked_scripts/context/stubs/unix/mtxrun,…

TeX Live allows remote attackers to execute arbitrary commands by leveraging inclusion of mpost in shell_escape_commands in the texmf.cnf config file.

Multiple integer overflows in dvipsk/dospecial.c in dvips in TeX Live 2009 and earlier, and teTeX, allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a special command in a DVI file, related to the (1) predospecial and (2) bbdospecial functions, a different…

Integer overflow in dvips in TeX Live 2009 and earlier, and teTeX, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted virtual font (VF) file associated with a DVI file.

Integer overflow in the predospecial function in dospecial.c in dvips in (1) TeX Live and (2) teTeX might allow user-assisted remote attackers to execute arbitrary code via a crafted DVI file that triggers a heap-based buffer overflow. NOTE: some of these details are obtained from third party information.
