Package : apache-log4j2
Version : 2.17.1-1~deb11u2
CVE ID : CVE-2025-68161
Debian Bug : 1123744
In Apache Log4j2, a Java Logging Framework, the Socket Appender does not
perform TLS hostname verification of the peer certificate, even when the
verifyHostName configuration attribute or the log4j2.sslVerifyHostName
system property is set to true. This issue may allow a man-in-the-middle
attacker to intercept or redirect log traffic under specific and hard to
exploit conditions.
For Debian 11 bullseye, this problem has been fixed in version
2.17.1-1~deb11u2.
We recommend that you upgrade your apache-log4j2 packages.

CVE ID : CVE-2025-14607 CVE-2025-14841
Debian Bug : 1122926 1123584
Two vulnerabilities have been addressed in DCMTK, a collection of
libraries and applications implementing large parts of the DICOM standard
for medical images.
CVE-2025-14607
Possible memory corruption caused by illegal attributes in datasets which
are processed by DcmByteString functions.
CVE-2025-14841
Invalid messages sent to dcmqrscp, the Image Central Test Node, may
trigger a segmentation fault due to a NULL pointer being de-referenced.
For Debian 11 bullseye, these problems have been fixed in version
3.6.5-1+deb11u6.
We recommend that you upgrade your dcmtk packages.

Package : gpsd
Version : 3.17-7+deb10u1 (buster)

CVE-2025-67268
CVE-2025-67269
Multiple vulnerabilities were found in gpsd, a service daemon that
monitors Global Navigation Satellite System (GNSS) receivers attached to a host
computer through serial or USB ports.
CVE-2025-67268
gpsd contains a heap-based out-of-bounds write
vulnerability in the drivers/driver_nmea2000.c file.
The hnd_129540 function, which handles NMEA2000 PGN 129540
(GNSS Satellites in View) packets, fails to validate the
user-supplied satellite count against the size of the skyview
array (184 elements). This allows an attacker to write beyond
the bounds of the array by providing a satellite count up
to 255, leading to memory corruption, Denial of Service (DoS),
and potentially arbitrary code execution.
CVE-2025-67269
An integer underflow vulnerability exists in the `nextstate()`
function in `gpsd/packet.c`.
When parsing a NAVCOM packet, the payload length is calculated
using `lexer->length = (size_t)c - 4` without checking if
the input byte `c` is less than 4. This results in an unsigned
integer underflow, setting `lexer->length` to a very large value
(near `SIZE_MAX`). The parser then enters a loop attempting to
consume this massive number of bytes, causing 100% CPU utilization
and a Denial of Service (DoS) condition.ELA-1617-1 gpsd security update
