Package : perl Vulnerability : heap buffer overflow Problem type : local (remote) Debian-specific: no CVE Id : CVE-2008-1927 Debian Bug : 454792
An editorial mistake resulted in DSA-1556-1 not correctly applying the required change, making it ineffective. This DSA has been reissued as DSA-1556-2. We apologize for the inconvenience. The text of the original DSA follows.
It has been discovered that the Perl interpreter may encounter a buffer overflow condition when compiling certain regular expressions containing Unicode characters. This also happens if the offending characters are contained in a variable reference protected by the \Q...\E quoting construct. When encountering this condition, the Perl interpreter typically crashes, but arbitrary code execution cannot be ruled out.
For the stable distribution (etch), this problem has been fixed in version 5.8.8-7etch3.
The unstable distribution (sid) will be fixed soon.
We recommend that you upgrade your perl packages.
