The Debian project has released security updates for two packages: gpsd and cjose. The gpsd package, which keeps track of GNSS or AIS receivers connected to a computer, has been updated to fix several security problems, including a serious issue that could allow unauthorized writing of data (CVE-2025-67268) and These issues have been addressed in version 3.22-4+deb11u1 of the gpsd package, which is available for Debian GNU/Linux 11 (Bullseye) LTS users. Additionally, a security update has also been released for the cjose package, which contains a fix for an AES GCM decryption routine vulnerability (CVE-2023-37464) in version 0.4.1-3+deb9u1 for Debian GNU/Linux 9 (Stretch) ELTS.

[SECURITY] [DLA 4441-1] gpsd security update

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.

For Debian 11 bullseye, these problems have been fixed in version
3.22-4+deb11u1.

We recommend that you upgrade your gpsd packages.

ELA-1616-1 cjose security update

Package : cjose
Version : 0.4.1-3+deb9u1 (stretch)

CVE-2023-37464

It was discovered that the AES GCM decryption routine of cjose, a C
library implementing the JOSE standard, incorrectly uses the tag length
from the actual authentication tag provided in the JWE instead of the
specified
fixed length of 16 bytes.
This allows an attacker to provide a truncated Authentication Tag and to
modify the JWE accordingly.
