Debian Security Advisory DSA-2265-1 firstname.lastname@example.org http://www.debian.org/security/ Florian Weimer June 20, 2011 http://www.debian.org/security/faq
Package : perl Vulnerability : lack of tainted flag propagation Problem type : remote Debian-specific: no CVE ID : CVE-2011-1487 Debian Bug : 622817
Mark Martinec discovered that Perl incorrectly clears the tainted flag on values returned by case conversion functions such as "lc". This may expose preexisting vulnerabilities in applications which use these functions while processing untrusted input. No such applications are known at this stage. Such applications will cease to work when this security update is applied because taint checks are designed to prevent such unsafe use of untrusted input data.
For the oldstable distribution (lenny), this problem has been fixed in version 5.10.0-19lenny4.
For the stable distribution (squeeze), this problem has been fixed in version 5.10.1-17squeeze1.
For the testing distribution (wheezy), this problem has been fixed in version <missing>.
For the testing distribution (wheezy) and the unstable distribution (sid), this problem has been fixed in version 5.10.1-20.
We recommend that you upgrade your perl packages.
