A buffer overflow in zoo may be exploited to execute arbitrary when creating archives of specially crafted directories and files.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| app-arch/zoo | * | < 2.10-r2 | >= 2.10-r2 |
zoo is a file archiving utility for maintaining collections of files, written by Rahul Dhesi.
zoo is vulnerable to a new buffer overflow due to insecure use of the strcpy() function when trying to create an archive from certain directories or filenames.
An attacker could exploit this issue by enticing a user to create a zoo archive of specially crafted directories and filenames, possibly leading to the execution of arbitrary code with the rights of the user running zoo.
There is no known workaround at this time.
All zoo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/zoo-2.10-r2"
A stack-based buffer overflow in zoo may be exploited to execute arbitrary code through malicious ZOO archives.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| app-arch/zoo | * | < 2.10-r1 | >= 2.10-r1 |
zoo is a file archiving utility for maintaining collections of files, written by Rahul Dhesi.
Jean-Sebastien Guay-Leroux discovered a boundary error in the fullpath() function in misc.c when processing overly long file and directory names in ZOO archives.
An attacker could craft a malicious ZOO archive and entice someone to open it using zoo. This would trigger a stack-based buffer overflow and potentially allow execution of arbitrary code with the rights of the victim user.
There is no known workaround at this time.

# emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/zoo-2.10-r1"
