Package : openh264
CVE ID : CVE-2025-27091
Debian Bug : 1098470
A heap-based buffer overflow flaw in the decoding functions of openh264,
a codec library which supports H.264 encoding and decoding, may allow a
remote attacker to cause a denial of service or the execution of
arbitrary code if a specially crafted video is processed.
For the stable distribution (bookworm), this problem has been fixed in
version 2.3.1+dfsg-3+deb12u1.
We recommend that you upgrade your openh264 packages.
For the detailed security status of openh264 please refer to its

Version : 1:27.1+1-3.1+deb11u6
CVE ID : CVE-2023-28617 CVE-2024-53920 CVE-2025-1244
Debian Bug : 1033342 1088690 1098255
Multiple vulnerabilities were discovered in GNU Emacs, the extensible,
customisable, self-documenting, real-time display editor.
CVE-2023-28617
Improper handling of file or directory names containing shell
metacharacters in the ob-latex Lisp library could allow the
execution of attacker-controlled code.
CVE-2024-53920
Several ways to trigger arbitrary code execution were discovered in
Emacs's support for editing files in its own dialect of Lisp.
These include arbitrary code execution upon opening an otherwise
innocent-looking file, with any (or no) file extension, for editing.
CVE-2025-1244
Improper handling of custom 'man' URI schemes could allow an
attacker to execute arbitrary shell commands by tricking users into
visiting a specially crafted website, or an HTTP URL with a
redirect.
For Debian 11 bullseye, these problems have been fixed in version
1:27.1+1-3.1+deb11u6.
We recommend that you upgrade your emacs packages.
