libcroco vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in Libcroco.
Software Description:
- libcroco: Cascading Style Sheet (CSS) parsing and manipulation toolkit
Details:
It was discovered that Libcroco was incorrectly accessing data structures
when reading bytes from memory, which could cause a heap buffer overflow.
An attacker could possibly use this issue to cause a denial of service.
This issue only affected Ubuntu 14.04 LTS. (CVE-2017-7960)
It was discovered that Libcroco was incorrectly handling invalid UTF-8
values when processing CSS files. An attacker could possibly use this
issue to cause a denial of service. (CVE-2017-8834, CVE-2017-8871)
It was discovered that Libcroco was incorrectly implementing recursion in
one of its parsing functions, which could cause an infinite recursion
loop and a stack overflow due to stack consumption. An attacker could
possibly use this issue to cause a denial of service. (CVE-2020-12825)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 20.04 LTS
libcroco-tools 0.6.13-1ubuntu0.1
libcroco3 0.6.13-1ubuntu0.1
Ubuntu 18.04 LTS
libcroco-tools 0.6.12-2ubuntu0.1~esm1
Available with Ubuntu Pro
libcroco3 0.6.12-2ubuntu0.1~esm1
Available with Ubuntu Pro
Ubuntu 14.04 LTS
libcroco-tools 0.6.8-2ubuntu1+esm1
Available with Ubuntu Pro
libcroco3 0.6.8-2ubuntu1+esm1
Available with Ubuntu Pro
In general, a standard system update will make all the necessary changes.

CVE-2024-36944, CVE-2024-36939)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS
linux-image-5.15.0-1065-oracle 5.15.0-1065.71
linux-image-oracle-lts-22.04 5.15.0.1065.61
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

[USN-6954-1] QEMU vulnerabilities
==========================================================================
Ubuntu Security Notice USN-6954-1
August 13, 2024
qemu vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in QEMU.
Software Description:
- qemu: Machine emulator and virtualizer
Details:
Markus Frank and Fiona Ebner discovered that QEMU did not properly
handle certain memory operations, leading to a NULL pointer dereference.
An authenticated user could potentially use this issue to cause a denial
of service. (CVE-2023-6683)
Xiao Lei discovered that QEMU did not properly handle certain memory
operations when specific features were enabled, which could lead to a
stack overflow. An attacker could potentially use this issue to leak
sensitive information. (CVE-2023-6693)
It was discovered that QEMU had an integer underflow vulnerability in
the TI command, which would result in a buffer overflow. An attacker
could potentially use this issue to cause a denial of service.
(CVE-2024-24474)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS
qemu-system 1:6.2+dfsg-2ubuntu6.22
