The imagemagick update (ELA-1515-1) resolves multiple security vulnerabilities that could lead to serious issues such as heap buffer overflows, memory leaks, and format string bugs. Notably, it addresses several CVEs resulting from unsafe size calculations and improper handling of format strings, particularly those containing consecutive percent signs (%%). The vulnerabilities affect various ImageMagick commands like `magick stream`, `magick mogrify`, and `montage`. Specific vulnerabilities include:
- CVE-2025-53014: Heap buffer overflow due to an off-by-one error in processing format strings.
- CVE-2025-53019: Memory leak in the `magick stream` command with multiple `%d` format specifiers.
- CVE-2025-53101: Stack overflow caused by internal pointer arithmetic under certain conditions.
- CVE-2025-55154: Unsafe size calculations leading to memory corruption.
- CVE-2025-55212: Crash triggered by improper geometry string handling in the `montage` command.
- CVE-2025-55298: Format string vulnerability enabling arbitrary memory overwrites.
- CVE-2025-57803: Integer overflow causing memory writes to adjacent heap memory.
- CVE-2025-57807: Security issues in `SeekBlob()` and `WriteBlob()` that lead to deterministic heap writes.
The ca-certificates-java update (ELA-1514-1) addresses a circular dependency issue between Java packages and system certificates, which was preventing necessary updates to system certificates. The new version (20230710~deb12u1~deb11u1~deb10u1) ensures that Java applications can properly access updated certificates, maintaining system security.
Overall, these updates are crucial for maintaining the integrity and security of Debian 10 systems, particularly for users who rely on image processing and Java applications. It's recommended for users to upgrade their systems promptly to safeguard against these vulnerabilities.
In extension, users should regularly monitor security advisories related to their software packages and consider implementing automated systems for updates to mitigate risks associated with unpatched vulnerabilities. Additionally, users should conduct periodic security audits and vulnerability assessments to ensure their systems remain secure over time
ImageMagick and ca-certificates-java updates for Debian 10 ELTS
Debian GNU/Linux 10 (Buster) Extended LTS has received two security updates. The imagemagick package has been updated to fix multiple security vulnerabilities, including heap buffer overflows, memory leaks, and format string bugs. The vulnerabilities (CVEs) listed include issues with processing format strings containing consecutive percent signs (%%), memory corruption due to unsafe size calculations, and arbitrary memory region overwrites. These updates address various commands within ImageMagick, such as magick stream, magick mogrify, and montage, which were found to be vulnerable to these security issues. Additionally, the ca-certificates-java package requires an upgrade to resolve a circular dependency between Java packages and system certificates.
