Debian DSA-800-1 : pcre3 - integer overflow

High Nessus Plugin ID 19570

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 5.5


The remote Debian host is missing a security-related update.


An integer overflow with subsequent buffer overflow has been detected in PCRE, the Perl Compatible Regular Expressions library, which allows an attacker to execute arbitrary code.

Since several packages link dynamically to this library you are advised to restart the corresponding services or programs respectively. The command 'apt-cache showpkg libpcre3' will list the corresponding packages in the 'Reverse Depends:' section.


Upgrade the libpcre3 package.

For the old stable distribution (woody) this problem has been fixed in version 3.4-1.1woody1.

For the stable distribution (sarge) this problem has been fixed in version 4.5-1.2sarge1.
