Security Vulnerabilities
- CVEs Published In August 2017
In ImageMagick 7.0.6-1, a use-after-free vulnerability was found in the function ReadWMFImage in coders/wmf.c, which allows attackers to cause a denial of service.
In ImageMagick 7.0.6-1, a memory exhaustion vulnerability was found in the function ReadPCXImage in coders/pcx.c, which allows attackers to cause a denial of service.
In ImageMagick 7.0.6-1, a memory leak vulnerability was found in the function ReadPESImage in coders/pes.c, which allows attackers to cause a denial of service, related to ResizeMagickMemory in memory.c.
In ImageMagick 7.0.6-1, a missing NULL check vulnerability was found in the function ReadMATImage in coders/mat.c, which allows attackers to cause a denial of service (assertion failure) in DestroyImageInfo in image.c.
In ImageMagick 7.0.6-1, a memory exhaustion vulnerability was found in the function ReadSUNImage in coders/sun.c, which allows attackers to cause a denial of service.
In shadow before 4.5, the newusers tool could be made to manipulate internal data structures in ways unintended by the authors. Malformed input may lead to crashes (with a buffer overflow or other memory corruption) or other unspecified behaviors. This crosses a privilege boundary in, for example, certain web-hosting environments in which a Control Panel allows an unprivileged user account to create subaccounts.
An issue was discovered in Varnish HTTP Cache 4.0.1 through 4.0.4, 4.1.0 through 4.1.7, 5.0.0, and 5.1.0 through 5.1.2. A wrong if statement in the varnishd source code means that particular invalid requests from the client can trigger an assert, related to an Integer Overflow. This causes the varnishd worker process to abort and restart, losing the cached contents in the process. An attacker can therefore crash the varnishd worker process on demand and effectively keep it from serving content - a Denial-of-Service attack. The specific source-code filename containing the incorrect statement varies across releases.
The ProcessMSLScript function in coders/msl.c in ImageMagick before 6.9.9-5 and 7.x before 7.0.6-5 allows remote attackers to cause a denial of service (memory leak) via a crafted file, related to the WriteMSLImage function.
Zoho ManageEngine OpManager 11 through 12.2 uses a custom encryption algorithm to protect the credential used to access the monitored devices. The implemented algorithm doesn't use a per-system key or even a salt; therefore, it's possible to create a universal decryptor.
ImageMagick 7.0.6-5 has memory leaks in the parse8BIMW and format8BIM functions in coders/meta.c, related to the WriteImage function in MagickCore/constitute.c.
