There is a heap-based buffer overflow within the main function. It allows an attacker to write data outside of the allocated buffer. The attacker has control over a part of the address that data is written to, control over the written data, and (to some extent) control over the amount of data that is written. Scope: local bu

There is a heap-based buffer overflow vulnerability in the DecodeLZW function. It allows an attacker to write a large amount of arbitrary data outside the boundaries of a buffer. Scope: local bullseye: resolved (fixed in 1.9+srconly-3+deb11u1)

CVE-2021-45911 [HIGH] CVE-2021-45911: gif2apng - An issue was discovered in gif2apng 1.9. There is a heap-based buffer overflow i... An issue was discovered in gif2apng 1.9. There is a heap-based buffer overflow in the main function. It allows an attacker to write 2 bytes outside the boundaries of the buffer. Scope: local bullseye: resolved (fixed in 1.9+srconly-3+deb11u1)

CVE-2021-45907 [HIGH] CVE-2021-45907: gif2apng - An issue was discovered in gif2apng 1.9. There is a stack-based buffer overflow ... An issue was discovered in gif2apng 1.9. There is a stack-based buffer overflow involving a for loop. An attacker has little influence over the data written to the stack, making it unlikely that the flow of control can be subverted. Scope: local bullseye: open

CVE-2021-45908 [HIGH] CVE-2021-45908: gif2apng - An issue was discovered in gif2apng 1.9. There is a stack-based buffer overflow ... An issue was discovered in gif2apng 1.9. There is a stack-based buffer overflow involving a while loop. An attacker has little influence over the data written to the stack, making it unlikely that the flow of control can be subverted.
