Title: 'Compress::Raw::Bzip2' Perl Module Remote Code Execution Vulnerability
Severity: CRITICAL
Description:
Perl is a multiplatform programming language. The 'Compress::Raw::Bzip2' module provides a low-level interface to the 'bzip2' compression library.
The 'Compress::Raw::Bzip2' Perl module is prone to a remote code-execution vulnerability that is triggered when the module is used to process compressed data. Specifically, the issue affects the 'bzinflate()' function of the 'Bzip2.xs' file and stems from an off-by-one error that may result in a heap-overflow condition.
Successful exploits may allow remote attackers to execute arbitrary code or cause denial-of-service conditions in applications that use the vulnerable module.
Versions prior to 'Compress::Raw::Bzip2' 2.019 are affected.
Affected Products:
- Compress::Raw::Bzip2 Compress::Raw::Bzip2 2.017
- Gentoo Linux
