Vulnerabilities 15
-
Critical 9.8
Buffer Overflow in Pillow
Pillow through 8.2.0 and PIL (aka Python Imaging Library) through 1.1.7 allow an attacker to pass controlled parameters directly into a convert function to trigger a buffer overflow in Convert.c.
-
Critical 9.1
Out-of-bounds Read in Pillow
An issue was discovered in Pillow before 8.2.0. There is an out-of-bounds read in J2kDecode, in j2ku_graya_la.
-
Critical 9.1
Pillow Out-of-bounds Read vulnerability
An issue was discovered in Pillow before 8.2.0. There is an out-of-bounds read in J2kDecode, in j2ku_gray_i.
-
High 7.5
Out-of-bounds Write in Pillow
An issue was discovered in Pillow before 8.1.1. In TiffDecode.c, there is a negative-offset memcpy with an invalid size.
-
High 7.5
Out of bounds read in Pillow
An issue was discovered in Pillow before 8.1.1. There is an out-of-bounds read in SGIRleDecode.c.
-
High 7.5
Pillow Denial of Service by Uncontrolled Resource Consumption
Pillow before 8.1.2 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for a BLP container, and thus an attempted memory allocation can be very large.
-
High 7.5
Pillow Uncontrolled Resource Consumption
Pillow before 8.1.2 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for an ICNS container, and thus an attempted memory allocation can be very large.
-
High 7.5
Pillow Denial of Service by Uncontrolled Resource Consumption
Pillow before 8.1.2 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for an ICO container, and thus an attempted memory allocation can be very large.
-
High 7.5
Potential infinite loop in Pillow
An issue was discovered in Pillow before 8.2.0. For FLI data, FliDecode did not properly check that the block advance was non-zero, potentially leading to an infinite loop on load.
-
High 7.5
Uncontrolled Resource Consumption in Pillow
An issue was discovered in Pillow before 8.2.0. For EPS data, the readline implementation used in EPSImageFile has to deal with any combination of \r and \n as line endings. It used an accidentally quadratic method of accumulating lines while looking for a li…
-
High 7.1
Pillow Out-of-bounds Read
In Pillow before 8.1.0, PcxDecode has a buffer over-read when decoding a crafted PCX file because the user-supplied stride value is trusted for buffer calculations.
-
Medium 6.5
Regular Expression Denial of Service (ReDoS) in Pillow
An issue was discovered in Pillow before 8.1.1. The PDF parser allows a regular expression DoS (ReDoS) attack via a crafted PDF file because of a catastrophic backtracking regex.
-
Medium 5.5
Pillow denial of service
An issue was discovered in Pillow before 8.2.0. PSDImagePlugin.PsdImageFile lacked a sanity check on the number of input layers relative to the size of the data block. This could lead to a DoS on Image.open prior to Image.load.
-
Medium 5.5
Insufficient Verification of Data Authenticity in Pillow
An issue was discovered in Pillow before 8.2.0. For BLP data, BlpImagePlugin did not properly check that reads (after jumping to file offsets) returned data. This could lead to a DoS where the decoder could be run a large number of times on empty data.
-
Medium 5.4
Pillow Out-of-bounds Read
In Pillow before 8.1.0, SGIRleDecode has a 4-byte buffer over-read when decoding crafted SGI RLE image files because offsets and length tables are mishandled.
