|Description||libpng before 1.2.37 does not properly parse 1-bit interlaced images with width values that are not divisible by 8, which causes libpng to include uninitialized bits in certain rows of a PNG file and might allow remote attackers to read portions of sensitive memory via "out-of-bounds pixels" in the file.|
|Source||CVE (at NVD; oss-sec, fulldisc, OSVDB, EDB, Metasploit, Red Hat, Ubuntu, Gentoo, SuSE, Mageia, more)|
|NVD severity||medium (attack range: remote, user-initiated)|
