1 CVE-2005-2096 DoS Overflow 2005-07-06 2012-10-30
7.5
User Remote Low Not required Partial Partial Partial
zlib 1.2 and later versions allows remote attackers to cause a denial of service (crash) via a crafted compressed stream with an incomplete code description of a length greater than 1, which leads to a buffer overflow, as demonstrated using a crafted PNG file.
2 CVE-2005-1849 DoS 2005-07-26 2010-08-21
5.0
None Remote Low Not required None None Partial
inftrees.h in zlib 1.2.2 allows remote attackers to cause a denial of service (application crash) via an invalid file that causes a large dynamic tree to be produced.
3 CVE-2004-0797 DoS 2004-10-20 2008-09-10
2.1
None Local Low Not required None None Partial
The error handling in the (1) inflate and (2) inflateBack functions in ZLib compression library 1.2.x allows local users to cause a denial of service (application crash).
4 CVE-2003-0107 DoS Exec Code Overflow 2003-03-07 2008-09-10
7.5
User Remote Low Not required Partial Partial Partial
Buffer overflow in the gzprintf function in zlib 1.1.4, when zlib is compiled without vsnprintf or when long inputs are truncated using vsnprintf, allows attackers to cause a denial of service or possibly execute arbitrary code.
5 CVE-2002-0059 Exec Code 2002-03-15 2008-09-10
7.5
User Remote Low Not required Partial Partial Partial
The decompression algorithm in zlib 1.1.3 and earlier, as used in many different utilities and packages, causes inflateEnd to release certain memory more than once (a "double free"), which may allow local and remote attackers to execute arbitrary code via a block of malformed compression data.
